Hello,
I've create a sample Swift package which uses binaryTarget to add local XCFramework dependency to a package. XCFramework itself contain two static libraries: One for iOS simulator, and one for iOS device. The result is that Xcode 13 crashes, and when build from command line there is an error, that doesn't help much.
Here is sample project download site:

Here is the result when building from command line:
swift build -Xswiftc "-sdk" -Xswiftc "`xcrun --sdk iphonesimulator --show-sdk-path`" -Xswiftc "-target" -Xswiftc "x86_64-apple-ios15.0-simulator" -v
/usr/bin/xcrun --sdk macosx --show-sdk-platform-path
