Create xcframework instead of Universal(fat) frameworks.

xcframework_generate.md

Advantages of xcframework

• Support for multiple platforms in the same framework.
• Support for Swift, Objective-C and C.
• Support for dynamic frameworks and static libraries.
• Support for Swift Package Manager.
• End of fat binaries.

Steps to create Aggregate target:

1. Open Current framework project
2. File -> New -> Target
3. Choose 'Other' tab -> Aggregate
4. I just named that target as 'MyFramworkUniversal'
5. Goto Build Phases -> Tap + Button -> New Run Script Phase. Then Add the code below.

#Gerenare device framework
xcodebuild archive -scheme ${PROJECT_NAME} -archivePath "${PROJECT_DIR}/build/${PROJECT_NAME}-iphoneos.xcarchive" -sdk iphoneos SKIP_INSTALL=NO BUILD_LIBRARIES_FOR_DISTRIBUTION=YES

#Generate simulator framework
xcodebuild archive -scheme ${PROJECT_NAME} -archivePath "${PROJECT_DIR}/build/${PROJECT_NAME}-iossimulator.xcarchive" -sdk iphonesimulator SKIP_INSTALL=NO BUILD_LIBRARIES_FOR_DISTRIBUTION=YES

#Generate xcframework for both arches
xcodebuild -create-xcframework -framework "${PROJECT_DIR}/build/${PROJECT_NAME}-iphoneos.xcarchive/Products/Library/Frameworks/${PROJECT_NAME}.framework" -framework "${PROJECT_DIR}/build/${PROJECT_NAME}-iossimulator.xcarchive/Products/Library/Frameworks/${PROJECT_NAME}.framework" -output "${PROJECT_DIR}/build/${PROJECT_NAME}.xcframework"

#Open directory where xcframework were generate
open "${PROJECT_DIR}/build"

Generate xcframework

Prerequisites

• Set Build Libraries for Distribution to Yes in Build settings.
• Set Skip Install to No in Build settings. Above steps are just to make confirm that the above flags are set.

Steps

• Select 'MyFramworkUniversal' scheme & run target as 'Any iOS Device'
• Build and Run
• Script will automatically open the directory where the xcframework were generated.
