PS: I can't see any errors. The app just tries to discover a reader.
Here's the full console log output:

Got it. And I'm guessing you are following this documentation? https://stripe.com/docs/terminal/payments/setup-reader/tap-to-pay
upper elbow
Yes
plain kelpBOT

👋 in your DiscoveryConfiguration what's the value of useSimulator ?
If it's true then your iPhone not showing up is expected since you're setting simulated to true
@upper elbow wanna make sure you saw my message above
upper elbow
It has false value
tawny mauve
Are you running a beta version of iOS?
upper elbow
No
tawny mauve
The SDK must be logging something out, are you sure these are the full logs?
upper elbow
Yes, I'm sure 🙂
tawny mauve
What version of the SDK are you running? And what country are you testing from?
upper elbow
What is the expected behavior? The documentation didn't say anything about it
pod 'StripeTerminal', '~> 2.0'
Serbia
tawny mauve
Is your stripe account located in a diff country?
We don't support Tap to Pay in Serbia
https://stripe.com/docs/terminal/payments/setup-reader/tap-to-pay?platform=ios#availability
upper elbow
Yes, it's based in USA
tawny mauve
Hmm I'm not sure if the real device also physically needs to be in the US or a supported country in order for this to work.
I assume you've been able to test using simulated reader already?
upper elbow
I assume you've been able to test using simulated reader already?
No. I wasn't able to get Tap to Pay working in any way.
tawny mauve
Can you try updating the SDK to the latest version?
The latest version for iOS is 2.23.1
https://github.com/stripe/stripe-terminal-ios
upper elbow
Installing StripeTerminal 2.23.1 (was 2.20.0)
Unfortunately, same result

Isn't this related to Tap to Pay feature?
tawny mauve
It is. What happens if you set simulated to true
upper elbow
Same, but this log line doesn't come up
tawny mauve
Can you share your complete code?
upper elbow
Like, the entire project?
tawny mauve
Like any ViewControllers that have code for terminal
upper elbow
I use Flutter, so no ViewControllers used
Here's a method called upon the app start:
func discoverReaders(completion: @escaping (Reader?, Error?) -> Void) -> Cancelable? {
self.completion = completion
let config = DiscoveryConfiguration(
discoveryMethod: .localMobile,
simulated: true
)
guard let terminal = terminalProvider.getTerminal() else {
completion(nil, NSError(domain: "", code: -1, userInfo: [NSLocalizedDescriptionKey: StripeTerminalError.stripeTerminalNotInitialized.message ?? ""]))
return nil
}
return terminal.discoverReaders(config, delegate: self) {error in
if let error = error {
completion(nil, error)
}
}
}
Hmm I'm not super familiar with flutter as we don't have first party support for it but typically you'd also need to implement a delegate method in order to listen for an update when readers are discovered
https://stripe.com/docs/terminal/payments/connect-reader?terminal-sdk-platform=ios&reader-type=tap-to-pay#discover-readers
// In your app, display the ability to use your phone as a reader
// Call `connectLocalMobileReader` to initiate a session with the phone
}```I have that:
// This delegate method can get called multiple times throughout the discovery process.
// You might want to update a UITableView and display all available readers.
func terminal(_ terminal: Terminal, didUpdateDiscoveredReaders readers: [Reader]) {
// Select the first reader we discover
guard let selectedReader = readers.first else { return }
// Once we've received battery level, don't expect further callbacks
guard selectedReader.batteryLevel != nil else { return }
completion?(selectedReader, nil)
}
The app works with physical Stripe reader just fine, FYI
tawny mauve
can you throw in a print statement in that function? Just want to make sure it's not getting invoked even when you set simulated to true
Are you writing your own flutter package for terminal SDK or using a third-party one?
upper elbow
None of that. I've written my own wrapper for StripeTerminal, just for the app.
Ok, it seems I'm getting a reader here! This condition filters it out: selectedReader.batteryLevel != nil
tawny mauve
Gotcha. That means it only fails on a real device, which I feel comes down to Tap to Pay on iPhone not being supported in the country your device is in
Apple might have some checks in the ProximityReader API that cancells the action for unsupported countries
upper elbow
Ok, thank you for helping @tawny mauve
