[Bug] building for any mac from an Intel mac does not build metacodable framework as universal

[robaho]

Building my project for "Any Mac" does not build the metacodable framework as universal, so when the application is started, it immediately crashes with:

The file is actually present at the path /Users/robertengels/Seahorse/DerivedData/Seahorse/Build/Products/Debug/PackageFrameworks/MetaCodable.framework/Versions/A/MetaCodable but it is not a universal binary so it doesn't load.

closing. I checked the file, and it has both architectures, so something else is happening.

I re-opened this, because I can't figure out what is going on. The build runs fine on Intel, but trying on Arm it fails with the above error - which makes me think it is something related to MetaCodable.

I built an archive in XCode, and copied the full application to the M1 machine, and I receive the same error - so it doesn't appear related to not actually finding the file.

Running file on the file, I see:

MetaCodable: Mach-O universal binary with 2 architectures: [x86_64:Mach-O 64-bit dynamically linked shared library x86_64] [arm64:Mach-O 64-bit dynamically linked shared library arm64]
MetaCodable (for architecture x86_64):	Mach-O 64-bit dynamically linked shared library x86_64
MetaCodable (for architecture arm64):	Mach-O 64-bit dynamically linked shared library arm64

@robaho can you share a sample project that can reproduce this issue?
