CI: Build Universal Binary 2 (x86_64, arm64) about midikit HOT 2 CLOSED

Not the same issue, but related: Mac Catalyst throws a similar error related to architectures.

Feedback from @PeterWier:

I have tried every workaround found on StackOverflow. Using VALID_ARCHS is strongly discouraged by Apple (VALID_ARCHS has actually has been removed from Xcode since the introduction of Xcframeworks). Using an Xcframework is probably the only solution. My workaround is to add MIDKit via drag and drop instead of the package.

OpenSSL-Universal is the most widely used Xcframework that works on all platforms including Catalyst and could be a good example: https://github.com/krzyzanowskim/OpenSSL

from midikit.

This works as a solution for CI:

xcodebuild build ... -destination "generic/platform=macOS,name=Any Mac"

xcodebuild test ... -destination "platform=macOS"

from midikit.
