App Crashes From ipa file but runs fine from Xcode?
I assume that you build your app with different build configurations basically using the Debug
configuration when you run it from Xcode and the Release
configuration for deployment as ipa. We had a similar issue with unexplainable bugs in the release configuration and figured out that the Swift Optimization caused the problem. For now we switched from Fast, Whole Module Optimization
to Fast, Single-File Optimization
for the release builds until we can narrow down the problem.
Hope that helps!
