I'm using SwiftUI inside my binary framework, I added SwiftUI.framework as Optional in Embedded Binaries and use @available so it compiles just fine with deployment target iOS 9.
However I cannot use it with xcodebuild, my commands :
xcodebuild clean archive \
    -project "${PROJECT_NAME}.xcodeproj" \
    -scheme ${1} \
    -configuration ${CONFIGURATION} \
    -destination "${2}" \
    -archivePath "${3}" \
    SKIP_INSTALL=NO \
    OBJROOT="${OBJROOT}/DependentBuilds" \
    BUILD_LIBRARY_FOR_DISTRIBUTION=YES | xcpretty
error message:
use of undeclared type 'View'
use of unresolved identifier 'UIHostingController'
P/s: -weak_framework SwiftUI in Other Linker Flags also didn't work
