Token Mismatch for Firebase Auth on MacCatalyst (works fine on iOS)

[ZComwiz]

Step 0: Are you in the right place?

Yes.

[REQUIRED] Step 1: Describe your environment

• Xcode version 12.1
• Firebase SDK version: 7.1.0
• Installation method: CocoaPods 1.10.0
• Firebase Component: Auth

[REQUIRED] Step 2: Describe the problem

When using FirebaseUI-Auth for iOS on Mac Catalyst to sign in via Text Message Auth it returns an alert: "Something went wrong. Please try again."

The console prints out an optional statement reading: Token Mismatch. The error does not occur on the iPhone or iPhone simulator.

Steps to reproduce:

Try typing in a number to MacCatalyst app on FirebaseUI v.9.0.0 (it didn't work on previous releases either) Get Above Error.

Relevant Code:

  UIViewController *vc = [[[UIApplication sharedApplication] keyWindow] rootViewController];
    FUIAuth *auth = [FUIAuth defaultAuthUI];
    auth.TOSURL = [NSURL URLWithString:@"https://app.com/terms"];
    auth.privacyPolicyURL = [NSURL URLWithString:@"https://app.com/privacy"];

    auth.delegate = [PFFirebaseDelegate sharedInstance];
    FUIPhoneAuth *phoneAuth = [[FUIPhoneAuth alloc] initWithAuthUI:auth];
    auth.providers = @[phoneAuth];
    [phoneAuth signInWithPresentingViewController:vc];

@paulb777 any clue what could cause that? Does Mac require a separate APNs upload to Firebase?

[ZComwiz]

@ryanwilson any idea where I should start investigating? I've looked into changing the APNS mode in the entitlements, made sure the bundleID was the same.. Anything in the provisioning profile used which might be at play?

[ryanwilson]

Looks like this is a FirebaseUI issue, I've transferred it there. Likely a duplicate as well, check out the notes here: #301 (comment)

Hope that helps, please share what you tried and if it worked or you're still seeing the issue.

[ZComwiz]

@ryanwilson I got it to work in debug mode by switching the entitlement file to development and the AppDelegate setup to .sandbox. However, switching it to Production and the AppDelegate setup to .prod doesn't work. I then archived the project and dug into the outputted app file and ran it and it still doesn't work in production. I wouldn't want to release to the App Store and have it break..

Is there harm in keeping the APNS in .sandbox mode while in production? Everything else is ready to ship! This is our last hurdle 🤞

cc @rosalyntan - can you please take a look and help find the answer here related to phone auth?

[strom2357]

We're tracking this internally at b/174266354

Since 3 days (maybe since Xcode 14) "Token Mismatch" started appearing for me out of the blue for phone auth (it used to work before and also does not work when i go back to commits where it used to work). So far it appears on any simulators. I managed to authenticate on iOS 16 simulators initially.

[nidegen]

My case is actually firebase/firebase-ios-sdk#10214

I think on macCatalyst it must be a smililar issue that push notification is unexpectedly available..

[ZComwiz]

@nidegen— Firebase Phone Auth has been a nightmare lately with many random internal errors and now this Token Mismatch for MacCatalyst even with 10.2.0. 🤯

[morganchen12]

Hey all, sorry for the delay. Can you check to see it if works now that firebase/firebase-ios-sdk#10214 has been resolved?
