Xcode – Import Frameworks on Apple Silicon

When I try to integrate a framework into an iOS app, then building will fail on an M1 MacBook (i.e., Apple Silicon), but does not fail on an Intel Mac. This occurs with the default build settings on the latest Xcode and also the latest Xcode Beta.
The error is as follows:

ld: building for iOS Simulator, but linking in object file built for iOS, file '/.../testm1/GooglePlaces.framework/GooglePlaces' for architecture arm64
clang: error: linker command failed with exit code 1 (use - v to see invocation)

I tried to check which architectures are included in the framework, then I am presented with the following info:

Command:

lipo -info GooglePlaces.framework/GooglePlaces

Output:

GooglePlaces.framework/GooglePlaces: Mach-O universal binary with 2 architectures: [x86_64cMach-O 64-bit object x86_64] [arm64]
GooglePlaces.framework/GooglePlaces (for architecture x86_64): Mach-O 64-bit object x86_64
GooglePlaces.framework/GooglePlaces (for architecture arm64): Mach-O 64-bit object arm64

and I also tried to check with ‘file’:

Command:

file GooglePlaces.framework/GooglePlaces

Output:

GooglePlaces.framework/GooglePlaces: Mach-O universal binary with 2 architectures: [x86_64cMach-O 64-bit object x86_64] [arm64]
GooglePlaces.framework/GooglePlaces (for architecture x86_64): Mach-O 64-bit object x86_64
GooglePlaces.framework/GooglePlaces (for architecture arm64): Mach-O 64-bit object arm64

Both commands show that it contains arm64.

Configuration:

MacBook Pro. 13” M1 2020,
16 GB
Big Sur 11.4
Xcode 12.5.1 & Xcode 13.0 (Beta 3)

Steps to reproduce:

1. Create a new project (select SwiftUI)
2. Integrate the GooglePlaces framework (as described in "Manually" here –> https://developers.google.com/maps/documentation/places/ios-sdk/start)
3. Import "GooglePlaces" in a file
4. try to build the project on an M1 Mac (Config 1)
5. observe the following error:

ld: building for iOS Simulator, but linking in object file built for iOS, file '/.../testm1/GooglePlaces.framework/GooglePlaces' for architecture arm64
clang: error: linker command failed with exit code 1 (use - v to see invocation)

Questions:

• Is this resolvable if I do not have control over the sources of the framework, just the built framework?
• How can I check, given the .framework file, if the framework supports arm64 for iphonesimulator, or only supports arm64 for iphoneos?

As suggested:

I excluded the arm64 for any ios simulators – then building is successful.
BUT: When I want to test the project without a host application the following error occurs:

2021-07-21 12:07:54.021519+0200 xctest[84732:517962] The bundle “testm1Tests” couldn’t be loaded because it doesn’t contain a version for the current architecture. Try installing a universal version of the bundle.

Program ended with exit code: 80

A workaround option:

• As not all frameworks support xcframeworks, launch Xcode with Rosetta. Then you will have no issues with any of those erros. I know that’s not the best workaround as Apple may remove Rosetta in future MacOS releases.
