Issue Description:

The building of my project (illegalinstruction.tar.gz) fails with "Illegal instruction: 4" (build log Build-target-ui_2021-06-25T16-04-59.txt).

If I comment out the body of the openMaps method in GuestEventView.swift source file (success.tar.gz), the build has success.

Hi Dario, we have deleted the attachments, since this bug tracker is public (feedbacks submitted are confidential) and people don't usually upload full apps.

Comment by Dario Scoppelletti (JIRA)

theindigamer (JIRA User), you are right about the attachments, but I was unable to reproduce the issue with a smaller app, and I am afraid no one will be able to solve the issue without my full app or at least the build log.

However, today I made few changes to the code and the build started fail again even with the openMaps method commented out.

The attachments are present in the feedback, so that should help in investigating the issue.

We stopped using the merge-module logic since Xcode 14. It was prone to this kind of crashes, it shouldn’t reproduce at this point. If you do see such an issue again please notify us here or open a new issue.
