Xcode 10 Signing Error: Frameworks/libswiftsimd.dylib: code object is not signed at all

Question

I've recently upgraded to Xcode 10.2.1 - clients have updated their devices to iOS 12.2 which caused features of mobile app to stop working (camera / qr scanner). So rebuilt my app in new Xcode (it's an ionic app). I can build and run in the simulator via Xcode but can't archive for distribution. Looks like a code signing error which I can't get around.

Have already tried re-assigning profiles, cleaning build, deleting derived data.

This is an issue with your libswiftsimd.dylib framework. are you using two xcode in your system? if yes then check your toolchain version under xcode -> preferance -> toolchain — Shauket Sheikh

In Xcode Menu - File -> Project Settings

Change Build System - to Legacy Build System and try

Let me know if it works
