I am on M1 (Xcode Version 15.4 (15F31d), MacOS 14.5 (23F79), Simulator IOS 17.4) and as far as I remember printing common usage register was possible. I am not sure why it stopped to work rid, rsi and etc (arg1 arg2 seems like still working).

class AppDelegate: NSObject, UIApplicationDelegate, UISplitViewControllerDelegate { var window: UIWindow? @objc func pendoEnterForeground() { print("pendoEnterForeground") } func applicationWillEnterForeground(_ application: UIApplication) { print("applicationWillEnterForeground") } func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool { NotificationCenter.default.addObserver(self, selector: #selector(pendoEnterForeground), name: UIApplication.willEnterForegroundNotification, object: nil) ... Th following works correctly on app with scenes BUT on old apps without scenes the following doesn't work on App launch (on the following foreground background it does work)i.e:pendoEnterForeground and applicationWillEnterForeground doesn't get triggered on first app launch.

I am trying to run Xcode 15 on macOS 15.4. As we need to build framework with older versions of Xcode. Any work around for it?

One of our customers provided us with stack log crash . The crash is coming from within the SDK. It seems that the crash start to happen on iOS 15. (We were unable to reproduce it on the simulator and haven't tried it on device yet) We would like to have more insights about the crash and its reason as according to the reference refernce there is no Termination Reason or Code.
