[MacCatalyst]: Can't determine the platform when creating an xcframework from rust libraries #107630
Description
Hello I'm using aarch64-apple-ios-macabi and x86_64-apple-ios-macabi as follow in my project:
CARGO_TARGET_DIR=$BUILD_FOLDER cargo +nightly build -Z build-std --target aarch64-apple-ios-macabi --release CARGO_TARGET_DIR=$BUILD_FOLDER cargo +nightly build -Z build-std --target x86_64-apple-ios-macabi --release lipo $BUILD_FOLDER/aarch64-apple-ios-macabi/release/$TARGET_NAME $BUILD_FOLDER/x86_64-apple-ios-macabi/release/$TARGET_NAME -create -output $BUILD_FOLDER/catalyst/$TARGET_NAME xcodebuild -create-xcframework -library $BUILD_FOLDER/$TARGET_NAME -library $BUILD_FOLDER/darwin_universal/$TARGET_NAME -library $BUILD_FOLDER/aarch64-apple-ios/release/$TARGET_NAME -library $BUILD_FOLDER/catalyst/$TARGET_NAME -output $TARGET_XCFRAMEWORK_NAME Was working fine until XCode 14.2 release which now produce:
error: unable to determine the platform for the given binary 'project/build/local/catalyst/libproject_rs.a'; check your deployment version settings This is the json target spec for MacCatalyst (aarch64):

rustc --version --verbose:
rustc 1.69.0-nightly (f3126500f 2023-02-02) binary: rustc commit-hash: f3126500f25114ba4e0ac3e76694dd45a22de56d commit-date: 2023-02-02 host: aarch64-apple-darwin release: 1.69.0-nightly LLVM version: 15.0.7 Maybe XCode have new requirements that the targets doesn't respect correctly? and therefore xcodebuild can't create an xcframework from any catalyst library?
