Every time I put my app into the background, I get the following error:
Can't end BackgroundTask: no background task exists with identifier 28 (0x1c), or it may have already been ended. Break in UIApplicationEndBackgroundTaskError() to debug.
This leads to remote notifications not being handled by my app while it's in the background. I don't use background tasks anywhere, and when I add a symbolic breakpoint on UIApplicationEndBackgroundTaskError, I get nothing useful in the stack trace. It simply breaks at the declaration of the AppDelegate class.
Any reason this might be happening? It's only started happening recently, so I'm wondering if it's related to iOS 13 or Xcode 11.
