ios - Installed App from TestFlight crashes due to alleged UISearchDisplayController

Question

I implemented Dark Mode with the current beta version of Xcode in a relatively old?app. I uploaded these to TestFlight for my?testers. However, this crashes immediately for anyone who has the public beta of iOS?13.

I've integrated Crashlytics into the app, and the cause of these crashes is as?follows:

UISearchDisplayController is no longer supported when using this version of?iOS. Please migrate your application to?UISearchController.

All UISearchDisplayController instances have already been replaced by the?UISearchController. The app doesn't use the UISearchDisplayController anymore. There is no longer any links to the UISearchDisplayController. Nevertheless, these crashes continue to occur, but only from the installations of?TestFlight.

If the app is installed directly with Xcode as a "Debug" or "Release" on an iPhone with the public beta, the crash does not?occur.

Does anyone have a solution for this problem?

Answer 1

After receiving the same error and finding no references to UISearchDisplayController across our app, we realized we needed to search for and replace searchDisplayController from within one of our storyboards. That corrected the issue after resubmitting a beta to?TestFlight.
