App crashes on launch; what does "Snapshot generation" and "denylisted" mean?

The full error I'm getting is Snapshot generation request for bundleID: example.bundle.id rejected due to the app being denylisted.

What does this error mean?

I am developing this app using Adobe AIR. Details:

  • Adobe AIR 33.1.1.476.
  • iOS 14.6
  • iPad Air 2
  • AdHoc installation

I found only 2 other results when searching for this error, and neither appears to have any applicable answers:

  1. https://stackoverflow.com/questions/65203246/nativescript-app-crashing-on-ios-14-2-when-using-an-mdm
  2. https://developer.apple.com/forums/thread/674421

Have you found a solution to your issue? I am experiencing the same problem and reported error message

I also had this error yesterday and the issue was that I had put my storyboards as Development Assets and Copy Bundle Resources and they should only be in Copy Bundle Resources.

Development assets are not copied when publishing your app so I basically had no storyboards in the ipa file.

I came to this conclusion by creating a Development Distribution ipa file via Product -> Archive and then renaming that .ipa to .zip which allows you to unarchive it. Then you get an app which you can right-click and explore the contents. In it you can see what your actual app bundle looks like and check what files you have and what you're missing.

You can also install the same .ipa file to a physical iPhone/iPad device and attach a debugger to the app's process and see a lot more meaningful errors than the crash logs.

Another useful thing is to tail the logs from your physical device via Mac's Console app.

Hope this helps someone because I struggled with it for 2 days since I'm a newbie.
