Hi 👋

So you are asking about this step in our guide?
https://docs.stripe.com/apple-pay?platform=ios&lang-ios=objc#present-payment-sheet

Yes I get an error "Argument type 'StripePaymentView' does not conform to expected type '_stpinternal_STPApplePayContextDelegateBase'" on this line of code "if let applePayContext = STPApplePayContext(paymentRequest: paymentRequest, delegate: self) {"

#

So I added this code as well "extension StripePaymentView: STPApplePayContextDelegate {
func applePayContext(_ context: STPApplePayContext, didCreatePaymentMethod paymentMethod: STPPaymentMethod, completion: @escaping STPIntentClientSecretCompletionBlock) {
// Create a PaymentIntent or SetupIntent on your server and return the client secret.
// Pass the client secret to the completion block.
}
}" but get this error "Cannot find type 'STPApplePayContextDelegate' in scope"

I'm not familiar with the way you are implementing the STPApplePayContext here. Can you trying starting with this code and let me know if this works?

@import Stripe;
@import StripeCore;
@import StripeApplePay;
#import <PassKit/PassKit.h>
@interface CheckoutViewController () <STPApplePayContextDelegate>
@property (nonatomic) PKPaymentButton *applePayButton;
@end
@implementation CheckoutViewController
- (void)viewDidLoad {
    [super viewDidLoad];
    // Only offer Apple Pay if the customer can pay with it
    self.applePayButton.hidden = ![StripeAPI deviceSupportsApplePay];
    [self.applePayButton addTarget:self action:@selector(handleApplePayButtonTapped) forControlEvents:UIControlEventTouchUpInside];
}

from our doc here: https://docs.stripe.com/apple-pay?platform=ios&lang-ios=objc#check-if-apple-pay-supported

Thats Objective-C and not Swift, do you have a Swift equivalent?

Oh yeah, I just saw the STPApplePayContextDelegate and figured you were using Objective C

import StripeApplePay
import PassKit

class CheckoutViewController: UIViewController, ApplePayContextDelegate {
    let applePayButton: PKPaymentButton = PKPaymentButton(paymentButtonType: .plain, paymentButtonStyle: .black)

    override func viewDidLoad() {
        super.viewDidLoad()
        // Only offer Apple Pay if the customer can pay with it
        applePayButton.isHidden = !StripeAPI.deviceSupportsApplePay()
        applePayButton.addTarget(self, action: #selector(handleApplePayButtonTapped), for: .touchUpInside)
    }

    // ...continued in next step
}
