Unable to init on visionOS.

[ZacharyLiu6]

Hi everyone,

I’m using version v1.4.4 of this plugin to support Apple Sign-In for my VisionOS application. I implemented login functionality by directly incorporating the MainMenu from the example scenes into my VisionOS scene and added the PressedAppleSignInButton method to handle click events for logging in.

However, when building for Vision Pro, I encountered some errors. It seems that the UnityPolySpatialAppDelegate does not implement methods related to window. Below is the Xcode console output during the app’s runtime:

*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[MyTestProject.UnityPolySpatialAppDelegate window]: unrecognized selector sent to instance 0x303d2bc20'
*** First throw call stack:
