@DTS Engineer this doesn't actually answer my questions though. I understand that the app is crashing because of a deadlock in CoreData, but as I mentioned I’m not doing any long running tasks. There have been instances where I’m not doing any work, other than just opening the application and then it crashes in the background. The "long running task" you reference has to be coming from the CloudKit integration with CoreData. Thats what I’m asking for a solution to. How do I prevent that from crashing the application, as CloudKit is internally managed.

This result does happen with a small sample project. I can't upload the zip file here, but it is attached to the original Feedback (FB16442048).
