I am trying to get a large (and working on Xcode 11!) project building in Xcode 12 (beta 5) to prepare for iOS 14. The codebase was previously in Objective-C, but now it contains both Objective-C and Swift, and uses pods that are Objective-C and/or Swift as well.
I have pulled the new beta of CocoaPods with Xcode 12 support (currently 1.10.0.beta 2).
Pod install is successful. When I do a build, I get the following error on a pod framework:
building for iOS Simulator, but linking in object file built for iOS, for architecture arm64
When I go run
lipo -info on the framework, it has: armv7s armv7 i386 x86_64 arm64.
Previously, the project had Valid Architectures set to: armv7, armv7s and arm64.
In Xcode 12, that setting goes away, as per Apple's documentation. Architectures is set to $(ARCHS_STANDARD). I have nothing set in excluded architectures.
What may be going on here? I have not been able to reproduce this with a simpler project yet.
