I am trying to implement sign in with apple with firebase. I cannot get around an issue where I get the following error when attempting a sign in: When running: Auth.auth().signIn(with: credential) { (authResult, error) in I get: nil credential = OAuthProvider.credential Optional(Error Domain=FIRAuthErrorDomain Code=17004 "The audience in ID Token [com.name.app] does not match the expected audience." UserInfo={NSLocalizedDescription=The audience in ID Token [com.name.app] does not match the expected audience., FIRAuthErrorUserInfoNameKey=ERROR_INVALID_CREDENTIAL}) Optional("The audience in ID Token [com.name.app] does not match the expected audience.") I have added my URL as stated on firebase to my identifier. To complete set up, add this authorization callback URL to your app configuration in the Apple Developer Console. Additional steps may be needed to verify ownership of this web domain to Apple.  More code: func authorizationController(controller: ASAuthorizationController, didCompleteWithAuthorization authorization: ASAuthorization) {   if let appleIDCredential = authorization.credential as? ASAuthorizationAppleIDCredential {    guard let nonce = currentNonce else {     fatalError("Invalid state: A login callback was received, but no login request was sent.")    }    guard let appleIDToken = appleIDCredential.identityToken else {     print("Unable to fetch identity token")     return    }    guard let idTokenString = String(data: appleIDToken, encoding: .utf8) else {     print("Unable to serialize token string from data: \(appleIDToken.debugDescription)")     return    }           print("credential = OAuthProvider.credential")    // Initialize a Firebase credential.    let credential = OAuthProvider.credential(withProviderID: "apple.com",                         idToken: idTokenString,                       rawNonce: nonce)     //Auth.auth().createUser(withEmail: T##String, password: T##String, completion: T##AuthDataResultCallback?##AuthDataResultCallback?##(AuthDataResult?, Error?) -> Void)    // Sign in with Firebase.    Auth.auth().signIn(with: credential) { (authResult, error) in           print(Auth.auth().currentUser?.uid ," credential = OAuthProvider.credential ", error)

I am attempting to make universal linking work, I created a file with the proper name and added it to my website (firebase deployed it), but it does not show up properly when I go to the URL, and it is not passed on here. - https://search.developer.apple.com/appsearch-validation-tool For more info: stackoverflow.com/questions/66927121/apple-app-site-association-json-not-showing-up I have implemented my association like it is done here, but when I then go to check the JSON by doing: day21.co/apple-app-site-association. This shows up: {"applinks":{"apps":[],"details":[]}} Rather than what I have in the file: ​ } ​ Here you can see the placement of the file, which I firebase deployed to hosting successfully. i.stack.imgur.com/tX5K2.png ​ What am I doing wrong? ​

Hi, I have an art app. On it, one user subscribes to another user for some $/month. Does Apple's Auto-renewable Subscriptions work for this? Or must I use stripe? I also asked this Reddit Q: rb.gy/tiyszl

I am wondering if a comments section in my app must-have report functionality for individual comments.

I am wondering if it is possible for me to launch 2 versions of my app. So that users downloading it would have a 50% chance of getting one or another version. For example, one would have one sort of camera and the other would have another kind (To compare the performance of app with one of the two cam layouts)
