Our app crashes intermittently when calling performSegue(withIdentifier:,sender:). The segue does exist, as most of the time it works fine. The destination view controller only has its view as a connection. Crash report excerpt below. Uploading the crash report isn't working for some reason, so I'll try to do so as a reply.
The stack trace shows searchForClientURL... as the last part of our code that gets executed.
I'm curious if I should look at things in our code that happen while the segue is being performed such as prepare(for:, sender:), the init of the destination controller, etc. or not because they're not showing up in the stack trace.
Thanks for any help!

Hi,
Our app has an HKObserverQuery and calls enableBackgroundDelivery(...)
While running on an iPhone the background wakeup happens. While running on an iPad, it doesn't. The app can successfully query for data while in the foreground on an iPad.
Is background delivery expected to work on iPad?
