iOS crash when testing on device - debug logs - ios

Question

I've begun testing my iOS app on my iPhone. Everything works great for a week or so and then my app starts to crash immediately when I try to open it. When I check the logs for my phone (Window-Devices-Select my iPhone), I see the following log messages.
<Notice>: Submitted job with label: UIKitApplication:com.app.App-Name[0x9fed][63]

I've googled for these error logs to try and find a solution, but no luck.
Any help would be much appreciated.

Answer 1

I had the same situation with an app which Bundle Identifier has been moved to another Apple Developer Team.
After Bundle Identifier was moved, a previous build was containing a provisioning profile which was no longer valid, and I got this error message in logs.
I guess the same happens if you delete the Provisioning Profile or if it is invalidated for whatever reason.
