iOS App life-cycle events are not being called when using custom AppDelegate

Since Qt 6.8.0, when using a custom AppDelegate on a iOS application, some life-cycle events are not being called.

The ones which are called are:

• didFinishLaunchingWithOptions{}
• applicationWillTerminate{}

However, the following events are not called:

• applicationWillResignActive
• applicationDidEnterBackground
• applicationWillEnterForeground
• applicationDidBecomeActive

I have attached a simple example project that reproduces the problem.

If you run this project on Qt 6.7.3 it works as expected. When Qt 6.8.0 is used, they are no longer called.

Having this events callbacks being called is crucial to manage application state.

Thank you!
