[tardy narwhal]

e prefix is just old 32bit, r prefix for real sexy hours

[primal perch]

some examples are like the mos 6502

z80 iirc

[upbeat wyvern]

esx = r0 rsx = x0 then? 😛

[primal perch]

so youd have to move your number from one into the accumulator, do your add

move it back if necessary

[tardy narwhal]

rax rbx rcx rdx rsi r8->r15

[tepid olive]

yea I guess

Pouring through armv7 thumb2 for 4 years is nothing compared to the pain I feel reading the x86 snippets from my book

Yeah

But that's just compiler logic

for the prologue and epilogue

[lethal ice]

arm64

[primal perch]

read the siguza write up it explains it @grave sparrow

[lethal ice]

arm64 > x64

true

[primal perch]

i linked above

[tepid olive]

Decrements the register you are storing/loading from before storing/loading to it @grave sparrow

[primal perch]

i cant really say which is better theyre both pretty fun

[tepid olive]

ARM64 is clearly better than x86 and its nonsense lol

[primal perch]

[tepid olive]

[tardy narwhal]

if you need fucked mnemonics it’s x86 where it’s at

[primal perch]

true

[lethal ice]

arm64 king

[tardy narwhal]

if arm copies it I will switch

[primal perch]

but at least you can load an address in one instruction

[tepid olive]

yea but at least arm doesn't use [] out of the context of a dereference

[primal perch]

yea but x86 has push / pop

[tepid olive]

like somehting that I know does

[lethal ice]

armv7 has push pop

[tepid olive]

okay you got me there

[primal perch]

yea but armv7

also kinda fun tho

[tardy narwhal]

VEXPANDPD or bust

[tepid olive]

I think the reason ida x86 decompiler costs so much is because x86 is full of bull shit lol

[primal perch]

Load Sparse Packed Double-Precision Floating-Point Values from Dense Memory

[tardy narwhal]

this is very true

[tepid olive]

and then they just said "hey, people are actually buying our 1800 dollar decompiler lets price the rest at that"

[primal perch]

probably

[tepid olive]

DENSE memory

[primal perch]

i bet the arm64 one was like 1/4 the effort

[tepid olive]

Probably some ancient thing from 1975

[primal perch]

granted still a lot of effort

but theres a lot less to do there

[tardy narwhal]

thats actually from avx512 lmao, it’s pretty recent

[tepid olive]

oh lmao

[primal perch]

yea the basic x86 instructions are pretty basic actually

[tardy narwhal]

but no fucking idea how to utilize it just yet

[primal perch]

basic twice

[tardy narwhal]

shep will u love me if I do a proper simd parser

[primal perch]

yea

[tepid olive]

wtf is aaa lol

[primal perch]

i havent even gotten into simd or any of that shit

[tepid olive]

AAAAAAAAAA

[primal perch]

ASCII Adjust after Addition.

not sure exactly what that means but nice

[tepid olive]

oh okay that makes sense

[primal perch]

Corrects result in AH and AL after addition when
working with BCD values.

[tepid olive]

Lemme just ASCII Adjust After Addition

[primal perch]

BCD ew

[tepid olive]

Actually bcd is pretty nice I used it for an OS project last semester

[primal perch]

theres a gameboy cpu instruction involving bcd and i think i copied half the implementation for it because i just didnt want to

lmao

[tepid olive]

I bet that isn't the same bcd I'm thinking of though

[tardy narwhal]

easy trick to simd is to think about it like stp from arm:
you store multiple values in the 128bit regs beforehand with the simd mov’s and then apply an operation to them. msvc usually can see if you actually need a loop or can just load in 4 values at once (for example with ints) and then apply the operation to all of them in one cycle

[tepid olive]

oh wow

[primal perch]

is it just for fast memory ops mainly

so like memcpy gets a boost

[tardy narwhal]

mainly for-loop optimizations and faster calculations

[primal perch]

fun

[tepid olive]

no don't you remember that x86 has its own memcpy with rep stosb lol

[tardy narwhal]

depends i guess on your workload

[primal perch]

sounds like hell to implement

can we get an F for gcc and clang devs

[tepid olive]

fr I can't imagine what it must have been like to implement compiler and decompiler logic for x86

[primal perch]

or maybe they just use the weed power too

[tardy narwhal]

oh it’s easy if by hand afaik, you can emulate it by allocating enough memory beforehand, memcpy and then have a function in assembly which correctly bitmasks and then applies your mathematical operation

or rotate the number and apply the op to the first 32 bits

rotate thrice and poof your hand written simd operation did almost the same as intels

[primal perch]

[tepid olive]

getting into that math shit

[tardy narwhal]

the cool part about it is you know that you’re working by definition within the number types’ bounds anyway so no overflow lmao

[tepid olive]

movzx == copy and zero extend?

[primal perch]

bruh i literally cant login to school after resetting. i use the exact passcode i just reset to and its incorrect

guess im not doing schoolwork

[tardy narwhal]

yes

[tepid olive]

Okay so I guess some mnemonics are intuitive

I think arm implies that zero extend for every mov

[tardy narwhal]

it’s primarily the simd/ sse ones which are hell to remember

[primal perch]

reminder that arm64 has eor as its xor mnemonic

[tardy narwhal]

because they make no fucking sense at times

[primal perch]

[tardy narwhal]

thank you for context switching to x86, i feel welcome again lmao

[tepid olive]

Lmao https://linux.slashdot.org/story/20/07/12/1729255/linus-torvalds-hopes-intels-avx-512-dies-a-painful-death

[tardy narwhal]

damn torvalds did x86 like that

:(

[tepid olive]

I love reading his rants

[tardy narwhal]

fuck avx though lmao

[tepid olive]

idk why he did quad 0 because a quadword in arm is 128 bits

why is the orig implementation in data lol

Put all your code in text

text == code data == data

[glacial matrix]

quad is for quadcore

[primal perch]

isnt a word 16 bits @tepid olive

am i too used to x86

[tepid olive]

in arm it's 32

[primal perch]

L

ok then just do .dword

[tepid olive]

I made that mistake as well going from arm to x86 lol

[primal perch]

its to initialize that pointer as 0

[tepid olive]

ohhhh

oh i see nvm

[primal perch]

i just mixed up the size i guess lol

[tepid olive]

I did not realize it was a pointer

Yes

anything that isn't code == data

So it goes in data

[primal perch]

in older games, code often is data

to save space

[tepid olive]

That specifies the size

for clang to reserve for your var

[primal perch]

i mean otherwise its just a label to whatevers after it

[tardy narwhal]

ah is this still for your swift hook thingy

[primal perch]

its a 64 bit variable with value 0

basically

[tardy narwhal]

oh gg

[tepid olive]

.dword 0 would reserve 8 bytes of zeros

[primal perch]

static long long nuts = 0;

[burnt niche]

Anyone have hopper 4.08 “paid version” working on big sur.

[tardy narwhal]

4.08 doesn’t seem to be the latest or is it actually

[primal perch]

killall Preferences @tepid olive

[ashen birch]

killall Preferences

[tepid olive]

@burnt niche Hopper is affordable though

[burnt niche]

4.0.8 is the one that works for me😂😂

[primal perch]

99$ for what it gives you is actually a bargain

[tepid olive]

for ida qword is always 64

[tardy narwhal]

i smell pirated copy

[burnt niche]

Yea but i am out of a job

[tepid olive]

I think that just comes from the fact that historically a word was 16 bits

Preferences?

[primal perch]

since soon there will be gpu accelerated linux gui apps running under windows pog

[burnt niche]

I got no money. I will definitely buy it after i have money

[primal perch]

wheres my msg

[tepid olive]

lmfao

[primal perch]

there it is

gone

[burnt niche]

It says “patched”. But my hopper is still demo mode

[tardy narwhal]

well asking for support on a old version is kinda pointless as people would be on the latest since hopper is fairly cheap

your best bet would be google

[primal perch]

true

[burnt niche]

Yea i am going to buy it first thing when i get a job

Asap

[tepid olive]

i'd use avx 512 for memmove and bzero and nothing more

[primal perch]

or just use ghidra

but ghidra ui kinda dook so

[burnt niche]

Ghidra seems like a nightmare ngl

[tepid olive]

Ghidra is very nice once you get used to it

You should give it a chance

[primal perch]

for being free its amazing

[tepid olive]

I hate hoppers ui

[burnt niche]

Should i use ghidra. Or ida 7.5 but on windows. So i have to reboot to windows every time

[tepid olive]

give ghidra a chance

Use it for like two weeks I think you'll find it good

[primal perch]

the decomp is miles better than hoppers

[burnt niche]

Alright bet

[tepid olive]

yea hoppers is very weird

one word on arm is 32 biuts

[tardy narwhal]

iirc that would be a pretty useful thing intuitively but costly in reality since simd is best used when loaded up first, for larger spaces it’s definitely a good idea

[tepid olive]

sizeof(void*) is 8 bytes cuz it's a pointer

the two aren't relatied

8 bytes just happens to be a dword in arm

@tardy narwhal oh okay

[primal perch]

sus

[tepid olive]

has anyone here bought a compiler before

I feel like that's a relic of the past

Like who the hell would buy a compiler

[primal perch]

no, thanks foss

[tardy narwhal]

yeah it’s that only drawback of simd instructions, the load up part. depending on the size msvc usually can deduce whether it’s better to use the ymm or even zmm regs

[primal perch]

bx lr
br x30

[tardy narwhal]

256 and 512bits respectively

[tepid olive]

what's msvc

That looks like you are declaring a function

especially with the underscore

[primal perch]

microsoft visual c compiler

[tardy narwhal]

ah i keep saying msvc but i mean microsoft’s c compiler

[tepid olive]

origImplementation: .dword 0

oh ok

[primal perch]

idk if thats the actual name but its microsoft c compiler

[burnt niche]

https://gist.github.com/yifanlu/e9965cdb148b550335e57899f790cad2 @tepid olive this seems nice

[tardy narwhal]

you’re right shep

[tepid olive]

Just install java

I think that'll be a headache

Java runs on 400 billion devices after all ™️

[burnt niche]

i already have it

[primal perch]

int main() {
  __asm {
    xor eax, eax
    ret
  }
}```

[burnt niche]

i used brew

[primal perch]

msvc is really neat because you can do this

[tepid olive]

oh

[burnt niche]

it was easy with brew

[tepid olive]

I installed it from ghidras website

[tardy narwhal]

I used to be a windows person, hence my refs to msvc lol, I cannot assrape clang just yet like you do shmoo

[tepid olive]

@grave sparrow rip use vim 😄

Lol

[burnt niche]

do you know how to get ghidra as a app?

[tepid olive]

I was able to crash the backend

with my special ridiculous use case

[tardy narwhal]

wtf

[burnt niche]

or do i have to ghidraRun everytime

[tepid olive]

@burnt niche Just install from the nsa website

#development message

😩

so sexy

pj

oh wait

yea do ghidrarun every time

https://nsa.org

[primal perch]

There is nothing here, at the moment, so please move along.

[tardy narwhal]

should be this channel’s description

[tepid olive]

[burnt niche]

it says ghidra was updated in 2020 decemeber

i thought it was abadoned

[tepid olive]

summer memories

making vr hax

I should make more vr hax

before facebook really decides to crack down on game mods on the quest

epic

[tardy narwhal]

better go out lit

[tepid olive]

lmao

[tardy narwhal]

than not lit

[primal perch]

no symbols thats an L

[tepid olive]

Put I already hacked the hell out of pavlov so I wanna do something different

yea it's ue4

but ue4 uses these blueprints, which idk what they are

but ue4 creates a "vtable" for them

[primal perch]

ive been trying to hack some 3ds games but not having symbols takes a lot longer and much guessing

[tepid olive]

That's the best way I can describe it

[tepid olive]

what app even is that again

and that vtable contains the function name before the functino lol

Ghidra

oh thatts ghidra

[primal perch]

guh heed ruh

[tardy narwhal]

lmao bruh

[primal perch]

[tepid olive]

and then from that blueprint vtable there's some init function which gives me the size of the object that vtable belongs to and its name lolol

so I can just hexdump different objects and compare them to see how memory changes cuz I have exact sizes

noclip in VR was sickening and hella fun

[primal perch]

unfortunately 3ds syscalls are wack so i havent gotten really far on that front

[tepid olive]

so was super speed

[tardy narwhal]

4:37am, i can finally rest

[tepid olive]

Almost fell over the first time I went superfast

[primal perch]

[tepid olive]

have a massive sleep

[tardy narwhal]

i hope you cut yourself on paper

[tepid olive]

loool

[tardy narwhal]

jk jk, love you lmao

[tepid olive]

yo hyper dash hax

actually idk it's too fast paced

I like playing it legit too much to make hax

Why have extensions on your makefile?

oh

vim 😄

vim will save you

[burnt niche]

what can i focus on to understand decompiled code as best as i possibly can

[tepid olive]

Learn c

You should focus on learning assembly also lol

[burnt niche]

would c++ work?

[tepid olive]

well arm instructoins are always 4 bytes so .align 4

C would be better

[lethal ice]

arm64

[burnt niche]

alright

[tepid olive]

Decompiler output is pretty much c

[lethal ice]

true

[tepid olive]

well, shortcutting it and relying on a decompiler when you reverse is a bad bad way to learn reversing

[primal perch]

many a time the decompiled output will be inaccurate or flat out bullshit so you need to resort to the disasembly

not really a problem with hexrays tho its op

[burnt niche]

this is why i got ida pro 7.5 on windows 🙂

[tepid olive]

pretty good output for me

[burnt niche]

why not?

[tepid olive]

oh true really learn about pointers and stuff before diving into asm

[burnt niche]

true but i am learning so much and i have gotten like 100 times better

[primal perch]

aight well im gonna go play some game or something so gn

@Developers

[tepid olive]

gn

[burnt niche]

yea i need to learn about pointers

what aspects of the language should i focus on and master before i dive into asm

[tepid olive]

Pointers and memory management'

look at how a struct is represented in memory

learn about endianess, etc

[burnt niche]

yea i made a tweak finally and i have managed to do all my goals

and more

i even added a new cell to a collectionview. which was tough for me

[tepid olive]

idk much about tweak dev lol

The only tweaks I made was something to put a battery percent on my iphone x

I dunno, and that will actually align 2^16 lol

so now that Ithink about it, do .align 2

[burnt niche]

i now completely understand the difference between class/instance methods. shared instances. properties. instance variables (kinda)

i resort to properties if the property exists instead of ivars

just need to learn how to set up debugserver / lldb

no clue on how to do it

do app development

read books

[gentle grove]

I need my dad's c book

Rewrite nekofetch in c

[burnt niche]

i read the swift book front and back from apple

the swift documentation

it was 800 pages

helped me a lot

i did hacking with swift

no i don't

[gaunt mesa]

hi

[burnt niche]

Is there any good explanations on pointers/memory management

Would love to learn more

[gaunt mesa]

the C book has it

[burnt niche]

Okay great

[gaunt mesa]

"The C Programming Language"

some edition i forget the newest one

[burnt niche]

Alright ill be sure to read that. Is it fine if i don’t know C? And i only read about pointer/memory management section. I know swift/objc

[gaunt mesa]

well

u should probably have atleast a little bit of C knowledge

as it won't use objective c runtime stuff

for the examples

[burnt niche]

Yea i have little c knowledge

Not a lot

I have java knowledge as well.

[lethal ice]

learn c it's the godfather of all things computer related

if you know C you know how computers work

[gaunt mesa]

rust

[lament mica]

based.

[burnt niche]

If i learn C. Will c++ be easier to work with?

[lethal ice]

no only align __text

just put .align 4 after .text and that's all u need to do

[gaunt mesa]

well yeah

C++ is pretty much the OOP version of C

[burnt niche]

Alright ill read the whole book. This week

[lethal ice]

no that means 4

[gaunt mesa]

why C, man if i got a C or a C+ i would get beaten for bad grades

[lethal ice]

p2align would mean 2^x

[gaunt mesa]

couldn't they have called it A

[burnt niche]

C for computers

[primal perch]

when the fuck did i say it was 2^4

ur thinking of p2align

[lethal ice]

.p2align 2

power of 2 align

@tepid olive

[primal perch]

[gaunt mesa]

shep is

[gentle grove]

C is based on b

[lament mica]

wait

qword is 128 bit

i'm thinking in windows mode

at least when dealing with simd q is used for 128 bit registers so i'd assume that means quadword

[lethal kayak]

so aside from the memes, is rust actually good as a language?

I guess all depends on the use case but

[lethal ice]

rust is theoretically better than c but i still like c better

[lapis vessel]

rust does have a lot going for it, one day I'll learn it properly

[lethal ice]

lmao oop wrong place

[cloud sundial]

Rust for me is like C but with daddy issues

The syntax is weird

[lapis vessel]

the syntax is weird, but it's got some really good design ideas. I don't really care about syntax when choosing a language

[tardy narwhal]

the only real thing it has going for it is having to not worry about memory management while being somewhat C

although kef did a pretty good summary of how a good chunk of people feel about rust lmao

[proper pivot]

I have a iPhone 6S Plus iOS 14.3 with Checkrain. I want to kernel debug my iPhone but I want to debug with a Windows PC with IDA. I have a mac as well.

[tardy narwhal]

@proper pivot peep into this: https://github.com/googleprojectzero/ktrw

[proper pivot]

Once I have it booted with the kernel extensions will it be possible to debug on my windows machine?

[tardy narwhal]

have you read the entirety of the readme yet

[proper pivot]

yes I tried on my mac to see if I could get it working

I was wondering if I could pass the usb serial connect to my Windows pc or run the ktrw_usb_proxy/ktrw_usb_proxy 39399 on windows

[tardy narwhal]

i doubt it since windows’ a bit finicky with usb, then again I don’t use ktrw that extensively currently

your best bet is still working from a mac

[proper pivot]

problem is I don't have IDA for Mac

[tardy narwhal]

it would technically count as piracy but just take ida & run it on your mac with wineskin or something analogous

@tepid olive you must be totally swamped and stressed doing gruelling boring work maintaining Procursus, the Homebrew guy says you have to be! https://twitter.com/mikemcquaid/status/1346749386689277952

@ck3mp3r Open source maintainers generally don’t take “I can see someone forking this” terribly well…

Twitter · Jan 6, 2021, 9:33 AM

this is probably false

why open source and then exert a monopoly-style emotion towards it

“yeah it’s my project and open source but i don’t want anyone to fork and get more traffic with it” or am i interpreting it wrong

[lime pivot]

his interpretation of open source is the saurik one where “fork” is a dirty word and the only acceptable type of fork is one that’s just about to make a PR to the upstream repo

[tardy narwhal]

bruh

[lime pivot]

love the way he tries to remind you you’re trapped with him

he’s not gonna change because nothing says he has to, but, the task of running a package manager + distro for macOS is so hard you’ll give up quickly

[tardy narwhal]

it’s somewhat disgusting to exert ownership in that fashion

are there any viable brew alternatives though

macports no?

[lime pivot]

I mean you did say “viable”

lol, that was harsh

MacPorts is definitely still a thing but I'm very surprised that it is

[tardy narwhal]

huh no lmao, all good

yeah i just remembered macports used to be a thing but i wasn’t entirely sure lol

procursus mac wen eta

[lime pivot]

I definitely used it before Homebrew became the Way To Go

I think the only thing Homebrew really brought to the table was that they had build servers providing prebuilt packages

[tardy narwhal]

so essentially anyone with a good grasp on makefiling/ building from source and providing a distribution server can stand up to brew

[lime pivot]

so I mean, I guess we just reinvented Fink 🤷‍♀️

oh I mean yeah, it's really down to 3 things IMO

1. provide the packages
2. provide the scripts that build the packages
3. maintain a community where additions/edits to those scripts are accepted

maybe 4. provide an interface to managing those packages that's familiar to use

[tardy narwhal]

you up for making another brew

[lime pivot]

maccursus™

[tardy narwhal]

with the double c in that I promote maccaroni™️ instead

[lime pivot]

no haven't you heard about the new McCursus™ burger from McDonald's®

[tardy narwhal]

oh shit you’re right, do I also get the new flat quadratic McCursus™️ fries with them or is that only in the McMenu small

oh my god the McCursus Burger with McFiles fries

the perfect combo lmao

[lime pivot]

McCursus™ sounds like someone came up with something crazier than ncurses for terminal UIs

[tepid olive]

Hate homebrew

[burnt niche]

@lethal ice @faint timber . You said cf_ are core foundation globals. What exactly would i search up to tell me that is a core foundation global. I know this is a really stupid question. I tried this. “Cf_ IDA pro” “Cf_ iOS” “cf_ variable ios”. My question is, what would you search up to get the relevant information. And also how do you know its a global variable. Is it possible to set/get that global variable. Which class is that global variable stored in. All the cf stuff is stored in the “Labels” folder. These are the type of questions i want to know. I just want to know what is the best way i could ask them since i don’t get any results when i search up. Also i want to know if theres any relevant material i could read up on to help me other than knowledge of C.

Btw when i search up cf ios variable. I did get to core foundation docs. But i also want to know how you could tell it was a global variable

Also for accessing global variables that already exist, i will be reading about IPC. As i read on google is a big topic to get a grasp of

[tepid olive]

is it defined locally?

[burnt niche]

Not sure what you mean bro

[tepid olive]

look at the function in ida

is it defined within that

[burnt niche]

“Cf_rematch_token”

[tepid olive]

look at the function in ida
is it defined within that

is it set or otherwise defined within the scope

[burnt niche]

I am not sure but all the cf variables are in the “labels” folder instead of “function” folders

[tepid olive]

That could be ghidra's way of labeling cf globals

but idk for sure

oh this is ghidra?

interesting

yea you can tell by the way the decomp vars are named

[burnt niche]

I might try it in ida pro when i get home

Im in vegas rn

@tepid olive is it possible to access these global variables through a tweak?

I might try to look up “rematch token” and see if i can find what class it might be in

[tepid olive]

its cf, probably not in a class...

[tardy narwhal]

you really need todo some C mate

diving into reversing blindly yielded exactly what was to be expected

unfocused noise

[naive kraken]

@upbeat wyvern sorry was asleep, regarding the arm64e problem, there was a change in the ABI in iOS 14, check out this github issue https://github.com/theos/theos/issues/563 and this twitter thread https://twitter.com/opa334dev/status/1344076615928721414?s=21

opa334 (@opa334dev)

Oh btw in case nobody has realized this yet, all tweaks will likely have to be recompiled with Xcode 12 to work on iOS 14 and up on arm64e devices :) and doing so will make them incompatible with 13 and lower, I really hope someone comes up with a clever solution for this lol

Twitter · Dec 30, 2020, 12:23 AM

(basically someone tested installing an arm64e app compiled with the Xcode 11 toolchain on iOS 14 and it does not work, only arm64e apps compiled with Xcode 12 are able to be installed on 14)

[tepid olive]

Yeah probably. And I second the fact that you should learn C and get a good grasp on pointers and memory management before diving into this

One thing at a time

"Mac? He's a great guy"

[glacial matrix]

Are you serious? Theos is just a set of makefiles and scripts. It’s up to gnu make to recognize those extensions, not us

[tepid olive]

Lmao

It can also recognize makefile and GNUMakefile

Just make a Makefile that only does include Stupid.mak so you can use that makefile @grave sparrow

[lethal ice]

i meant google the specific variable name

looking up "cf" will give you 200000000000 search results

[burnt niche]

Oh okay got it

[lethal ice]

i dont know anything about the specifics of that global

[glacial matrix]

#WontFix #OutOfScope

[lapis vessel]

@lethal ice tbf googling "cf_rematch_token" yields exactly 0 results

[tepid olive]

do i learn c/c++ or js/ts

can't decide

[primal perch]

c

[tepid olive]

uhh ok

doubt i'll do it because i don't have uses for c

might just learn basics to have a way to understand it

else i'll do typescript

[tardy narwhal]

i mean that’s a good argument to base your decision on: use cases

[tepid olive]

yea ofc

People really use xcode as an ide bro

Can you believe that

Yeah

From what I can tell it has really good lldb integration though

Cringe

[tepid olive]

when i figure out how to compile my shit from command line i'll use nano only

For debugging on the phone

else Xcode is pretty good

for autocomplete stuff too

If xcode works so does xcodebuild

xcode-select: error: tool 'xcodebuild' requires Xcode, but active developer directory '/Library/Developer/CommandLineTools' is a command line tools instance
kms

xcode-select

i did it

lmao

Do it better

Literally tells you how to fix it

xcode is installed

lul

and command line tools are there too

xcode-select

Select xcode

thanks

can i like not make it clean every time

fuckin slow tf

Xcode is always slow

ok

xcode is still better apparently

Just write a makefile

because it doesn't open auto

so yea

too lazy to make a makefile

[tepid olive]

p l e a s e

won't happen but please apple

ok it works now

pretty fun

i'll keep using xcode tho because it's more fun to use than vscode

I have a UISlider in my tweak's pref bundle. When I slide it to change the value everything works fine, but as soon as I exit settings and come back it resets. Any ideas as to why this might happen. I've tried googling it but I didn't get much help

[tepid olive]

ok

[late ridge]

Normally, I would use cephei to get the value from the key in the plist, but I'm not sure how to do that with a custom slider

I guess I could use the cephei slider.. I wanted to learn how to do it with my own class though

oh wait..

Hi, i created a bash tool on iOS. But I cannot use autotouch io.popen to call it though autotouch can be able to call activator and another shell app normally.

[tepid olive]

man autotouch isn't something you can use

it's gone from repos anyways

and made by a pirate

[restive ether]

i do not think that’s true homie

[tepid olive]

Anyone got an iOS 12 device with Procursus that can test something for me?

[tepid olive]

autotouch is made by comex and he's the IAP crack tweak guy

@tepid olive ok next time check before saying things

bc these whitenames are just gonna repeat what u say

[tepid olive]

saurik probably thinks that

fair enough

i was 100% sure they were the same person

my brain plays me tricks

claimedURLSchemes was added in 13

ok, gotta find a method to get url schemes

kind of a bummer you can't hook from it

would be easier then

[burnt niche]

alright here is my daily stupid question of the day. i call this method -(void)makeAPIRequest:(id)arg1; from a class named serverhandler. i then nslog the argument and this is what i get. NSLogify makeAPIRequest : <APIRequest: 0x280650450> where APIRequest is a another class. So the argument is a pointer to apirequest? i tried to look up the address in flex but it says it does not exist. is there any way i can get more info than just a address?.

[tepid olive]

what exactly does that do, can't you just read it from the Info.plist

[restive ether]

shows what url said app uses

[tepid olive]

I found a way on ios 12

[restive ether]

Name: Weather  
BundleID: com.apple.weather  
Path: /private/var/containers/Bundle/Application/B4D808B2-234C-4EE9-BF40-B016FFBF7ECF/Weather.app  
Container: /private/var/mobile/Containers/Data/Application/47BB83AF-8DEA-4AED-A710-B4656973C75B

Type: System  
Removeable: true  
URLScheme: weather

true

[tepid olive]

LSApplicationWorkspace.h has

-(id)publicURLSchemes;
-(id)privateURLSchemes;

[twilit jungle]

<APIRequest: 0x280650450> means there was an APIRequest object at 0x280650450 when you logged that.

By the time you try to look at that object in FLEX the request is most likely deleted.

[tepid olive]

fun fact: you can't open private URL schemes in Safari but you can with Shortcuts

you can also just do: shortcuts://x-callback-url/run-shortcut?x-error=weather://

[burnt niche]

is there any way i can get more information on that object?

[tardy narwhal]

flex

[misty cradle]

^^

object explorer

then type the address 0x280650450 in

and it'll show you the object and everything else

if its still in memory
