Bugsnag does not compile for visionOS with Xcode 15 Beta 2

[marcpalmer]

Describe the bug

You cannot compile a target for visionOS if it imports Bugsnag as a dependency.

This is because Bugsnag uses #if TARGET_OS_IOS in many places and Apple has "changed the meaning" of this in the sense it cannot be used to identify builds for iOS devices only. It identifies that it is an iOS-like platform, and Bugsnag is gating some code using this that is not valid on visionOS.

Steps to reproduce

1. In Xcode 15b2, Open an iOS project that uses Bugsnag via SPM
2. Go to the app target and go to General > Supported Destinations
3. Remove the "visionOS (Designed for iPad)" destination if present
4. Add a "visionOS" destination.
5. Agree to the suggested changes
6. Build project
7. You will see compile errors about endGeneratingDeviceOrientationNotifications being unavailable in visionOS

Environment

• Bugsnag version: 6.27.0
• iOS/tvOS/macOS version(s): visionOS 1.0 beta
• Simulator or physical device: Simulator
• Xcode version: 15.0 Beta 2

Explanation

This causes an issue with this code in BugsnagClient specifically when building for visionOS:

#if TARGET_OS_IOS
    [[UIDEVICE currentDevice] endGeneratingDeviceOrientationNotifications];
#endif
}

This endGeneratingDeviceOrientationNotifications API is not available at all on visionOS so it will not compile.

The solution provided by Apple engineers is to check that TARGET_OS_XR is not also set, something like:

#if TARGET_OS_IOS && !TARGET_OS_XR
    [[UIDEVICE currentDevice] endGeneratingDeviceOrientationNotifications];
#endif
}

Hi @marcpalmer. Thanks for raising. It is something we are aware of and currently discussing, I'm going to close this in favour of #1565 which I believe is a duplicate of exactly what you are suggesting.

Thanks @johnkiely1 I added a comment there.
