So far, my app has been running normally. I made an update on a page in the app and when I wanted to test it in the previewer the screen was suddenly white. I thought I might have forgotten the entry point, but it was set. Even after reloading and resetting the changes made, the screen remained white. And yes - there is data. I absolutely have to have the version checked by Apple, but it will never work with the white screen!
Thank you very much for your time.
