I am getting the same thing on app I am upgrading from swift 1 and some Objective C ones. No Idea what this is.
I get this along with a crash on iPad running iOS 11. The app works perfectly well on iPads with iOS 10. I've submitted a bug report to Apple.
Hundreds of my users are reporting crashes on this app designed to run on iOS 9.3 or better. No response from Apple yet.
Same problem: Xcode 11.4.1, iOS 13.4.1, app set available from iOS 8.0, running on actual iPhone.
Seems to result in blank or misconfigured table cells on 1st launch, but:
- blank cell is resolved on subsequent launches, and
- misconfigured cells are resolved upon scrolling down then back up.
I also converted from Objective-C to Swift and now am getting this message. Hmm... something in the background with loading a xib hanging around?
I deleted the `Launch Code.xib`, cleaned everything, and rebuilt. I haven't seen the error again so far...
Note: I made sure the `Launch Screen.storyboard` was selected in the target's `Launch Screen` setting, and that the `main.storyboard` was selected for the Deployment->Main Interface setting before deleting/rebuilding.
