iOS crash: App does not run anymore when built with Xcode 15.3 for iOS 17.4

[gabrielbiga]

Since my personal iPhone 12 updated to the iOS 17.4 (21E219) version I cannot run my app anymore. At first, I thought that was only my APP, so I tried to run the Angular example and I got the exact same error.
The weirdest thing is if I run the app on the physical iPhone, it crashes giving the error, but if I run it on an emulator, nothing happens, the app runs ok.
I just sent an APP for AppStore review and it was rejected because it's crashing at the splash screen.

I had some success replacing the NSURLSessionConfiguration call with NSURLConnection patching inside the @nativescript/core package, but the app is still failing at some native access. Maybe the native bridge is broken at the latest version + latest SDK.

***** Fatal JavaScript exception - application has been terminated. *****
  NativeScript encountered a fatal error:

There seems to be an issue with Xcode 15.3.0, I hit the same issue with crash on launch on device, but OK on simulator. Can you downgrade to 15.2.0? That resolve the issue for me.

I have suspicions it's down to a new clang option that's being added (-fdefine-target-os-macros) but that hasn't been added yet (but the 15.3 headers rely on).. but I'm not 100% sure (digging into it at the moment).

Hello @apburgess thanks for your answer and your investigation, but the error was just fixed by #242.
I just tested and it back everything 100% to normal. Many thanks all who put some effort on it!
