I need help understanding the root cause to resolve. Overwhelmed by the log :(

This is the Swift compiler crashing. The compiler should never crash no matter what your code looks like, so this is by definition a bug.

A good first step here is to try to reproduce the problem on a ‘clean’ machine. This has a bunch of a benefits:

  • If you can’t reproduce it, you know that it’s tied to your environment in some way.

  • You can reproduce it, you’re somewhere towards be able to file an actionable bug report.

  • You can also use your reproduction steps to try out workarounds.

I usually use a VM for this sort of thing, but if you don’t have that set up you can create a new local user account and try it there.

Share and Enjoy

I also faced this issue since Xcode 14.3

  • Xcode 14.2 It works fine

Swift Optimization with -Onone is working. But -O is not working.

I also posted it https://github.com/apple/swift/issues/64859

/Users/yoshi/Library/Developer/Xcode/DerivedData/TT-galmzhtedumvzaewgvxgohgbvzou/Build/Intermediates.noindex/TT.build/App Store-iphonesimulator/TT.build/DerivedSources/GeneratedAssetSymbols.swift

  2. While running pass #16730432 SILModuleTransform "DeadFunctionAndGlobalElimination".

Also experiencing this. I isolating the issue to some recent Firebase pod changes. In my case moving from 10.17.0 to 10.24.0 but haven't figured out anything further.
