Description:

I am new to IOS development. I followed the tutorial on Apple's official website to learn, and the URL is below: [https://developer.apple.com/tutorials/app-dev-training/creating-a-storyboard-app)

However, when I run the app, the app's screen is always blank. I'm pretty sure I followed by the official tutorial step by step.

What I have tried:

  1. Check the mark of "is Initial view controller" at Main.storyboard

  2. Cancel the mark of "is Initial view controller" at Launch.storyboard(if I didn't cancle the mark, the label "Im a label" of Launch.storyboard will show up for one second and then come up a blank screen.)

  3. Delete the view controller and add a new one.

  4. I check the Info, it seems fine:

My Environment:

  1. Xcode: 13.1
  2. Simulator: ios15
  3. Simulator: iphone 12 pro

Looking forward for response, and thank you~

Launch.storyboard

  • Should definitely not be your Initial View Controller
  • This is shown very briefly on app launch, while the app's initial view is prepared

Table View Controller

  • In Main.Storyboard, this is your Initial View Controller
  • If it is showing as a blank screen, then that is down to your code
  • e.g. the Table View has no rows, or the row content is empty

If you share the code for your Table View Controller, it should be possible to see the problem.
