iOS App Goes to Black Screen

Question

I am using a Launch Screen storyboard as well as a Main storyboard in my Swift app. Sometimes the app will show the launch storyboard and then go to a black screen. Other times it correctly goes to the Main storyboard entry point. It almost seems like it is build-dependent in that if I clean and rebuild a few times, a build pop out that behaves properly. Any ideas what may be causing this?

To add some clarification:

• The SplashScreen.storyboard is set in the target settings (good question).
• This happens both on real devices and in simulator BUT NOT ALWAYS.
• I am not doing any networking (synchronous or otherwise) in this stage
• The blackout seems to happen only when transitioning to one specific view
• The code for the view's viewWillDisplay and such executes even when blacked out, just nothing VISIBLE is displayed

This might help: I put in the following code in the offending view:

override func viewDidAppear(animated: Bool) {
    print(self.view.layer.bounds.width);
    print(self.view.layer.bounds.height);

}

When the black screen issue occurs, I get 260 and 17. When the view presents correctly, I get the 5s (simulator) dimensions of 320 and 568. Does that help anyone help me?

Answer 1

I was faced with the same issue in my device. I managed to fix it by setting the application's main interface via xcode: MyApplication → Main Interface → LaunchScreen.storyboard (or Main.storyboard).

Cheers! :)
