Current behavior

Even when initialising app check as per https://github.com/robingenz/capacitor-firebase-plugin-demo/blob/main/src/app/modules/firebase-app-check/firebase-app-check.page.ts, when running in an iOS 17 simulator I get

[error] - {"errorMessage":"The operation couldn’t be completed. The attestation provider DeviceCheckProvider is not supported on current platform and OS version.","message":"The operation couldn’t be completed. The attestation provider DeviceCheckProvider is not supported on current platform and OS version."}
⚡️  [error] - [2024-05-23T15:57:17.076Z]  @firebase/app-check: {"errorMessage":"The operation couldn’t be completed. The attestation provider DeviceCheckProvider is not supported on current platform and OS version."}

This is despite setting debug to true on initialise:

FirebaseAppCheck.initialize({
    debug: true
  }

Which should use the AppCheckDebugProviderFactory. It should also be using AppAttest instead of DeviceCheck however after reading up on some similar issues I believe that's a red herring. It seems that the real issue is that in this plugin, Firebase.configure() is being called BEFORE the AppCheck provider factory is being initialised, which makes it default to DeviceCheck, when as per the docs it should be called after.

I think the solution will simply be to remove the override init that configures firebase before calling the initialize provider function. I've tested adding the DebugProvider init code to my AppDelegate so that it happens before the Capacitor code is executed and that has worked.

Expected behavior

For the AppCheckDebugProvider to be used as expected when debug is enabled.

Yes, this is a known issue. We'll fix this in the future. I close this as duplicate of #453.
