swift_initClassMetadataImpl EXC_BAD_ACCESS with Xcode 11.2.1

Question

I recently updated to the Xcode 11 beta, and my code seems to crash at a Swift runtime function swift_initClassMetadataImpl with an EXC_BAD_ACCESS error.

Is there a temporary workaround for this?

Edit: This issue is still present on Xcode 11.2.1 GM.

Answer 1

Try to do this, works for me (checked in 11.2 GM)

Temporary workaround that fixes it:

-Go to Project Target/Build Settings
-"Dead Code Stripping" to NO

found here: https://github.com/ReactiveX/RxSwift/issues/2099#issuecomment-548978168

and here https://bugs.swift.org/browse/SR-11564

or you can get the previous version here

and yes, the issue exists in 11.2 GM
