Xcode12 beta4: Custom frameworks not compiling in iOS simulator


  1. Using Xcode 12 beta4 generated custom frameworks.

  2. frameworks are successfully compiling in iPhone devices and same frameworks not compiling in iOS simulators.

  3. In Xcode 11 custom frameworks are working fine for both devices and simulators.

I need to change any build settings as Valid Architectures option removed in Xcode 12 and also The stand-alone system assemblers for i386, x86_64, and arm are deprecated and may be removed in a future Xcode release.


We had this same issue and solved it by tweaking the VALIDARCHS to only build x8664 for iOS sim debug builds. Obviously not a long term solution with arm64 Macs on the horizon.
