App crashing only when submitting it for review (NSInvalidUnarchiveOperationException)

Question

Hello,has anyone seen a problem similar to this one? Any hint?The application is built with Catalyst and reviewers say it crashes on start, while it works flawlessly on my Mac. The stacktrace I got from the reviewers seems to point to something wrong with the NIBs compiled from the storyboard?Application Specific Information:*** Terminating app due to uncaught exception

My project compiled and ran without any crashes yesterday using XCode 11.1. I updated to XCode 11.2 today and now my build crashes with this exact error.  Please let me know if you find a solution.

yo_asakura · Answer

Same here! It happens in iOS 11.0.1 when I test. No problem on iOS 13. I think there&#x27;s something to do with UITextView. The app crashes only when I try to open a screen with a TextView. The TextView is added via Storyboard. No problems if I add it via code.

WebFM · Answer

I ran into the same problem, the app will crash on any version before iOS 13.2, which include 13.1.2

I am also facing same issue. It suddently started crashing in real device.

I&#x27;m only seeing crashes on my custom UITextView on my (devices) iPad Pro and iPhone X but it runs fine on my iPhone 7. Simulator works fine on all.

AlexMCC · Answer

Looks like we need to wait for Xcode 11.2.1. Hopefully this will happen soon.

Same issue as this one: https://forums.developer.apple.com/thread/125287If you run on iOS 13.2 simulator it won&#x27;t crash but I try a older IOS Simulator like 11.4 it will crash as above (Xcode 11.2).No problems with Xcode 11.1 other than debuging wont work with iOS 13.2 devices.

Phantom59 · Answer

I can confirm that replacing my Storyboard based UITextView with one programatically generated no longer crashes.See this SO thread for more details.

Wiz · Answer

that other thread suggests using Xcode 11.1 but I had the problem originally with 11.1, so that won&#x27;t help.Taking views out of storyboards is a major PITA: you&#x27;ll have to recreate a lot of constraints, that might vary by traits, etc... InterfaceBuilder would really benefit from a "replace view with" that would let you swap, for instance, an UITextView with a UIView while keeping the same size and constraints.

ykphuah · Answer

Bummer, just faced this issue. Might it be that we are all running the latest MacOS but the reviewers are not?

Wiz · Answer

well, they definitely had a different build number for 10.15.1 than I have. Anyway, if it crashes on 10.15.0 is not good.
