Termination Reason: CODESIGNING 2 Invalid Page : Normally that means your signing got the problem.

Pls try: 1.Re-sign the Application 2.Check Build Configuration

Thanks for the reply @Tom_k. I think there’s a problem with the audio because the crash log only appears when I open the app, then kill it, and repeat this process 6–7 times.

@Tom_k i have already fixed that bug with code like this in xcode

- (void)applicationWillTerminate:(UIApplication *)application {
    [[SDKWrapper shared] applicationWillTerminate:application];
// [appDelegateBridge applicationWillTerminate:application];

       
}

The crash log no longer appears after multiple attempts. However, does commenting out the code as shown have any impact?

The commented code, which handle cleanup tasks related to the Cocos engine, such as:

  • Save game data and user progress
  • Release engine resources and memory
  • Stop running tasks and threads
  • Execution engine’s exit cleanup logic

“applicationWillTerminate” event which called when user quits the application. If forcefully killing application may lead to unexpected issues including crash.
