I have a Carthage framework A that is dependent on another of my Carthage frameworks B. That framework B is dependent on a framework C. My Cartfile does not have C listed, but as the docs describe, it is downloaded on carthage update. In my Run Script I have:
$(SRCROOT)/Carthage/Build/iOS/A.framework
$(SRCROOT)/Carthage/Build/iOS/B.framework
$(SRCROOT)/Carthage/Build/iOS/C.framework
And:
$(BUILT_PRODUCTS_DIR)/$(FRAMEWORKS_FOLDER_PATH)/A.framework
$(BUILT_PRODUCTS_DIR)/$(FRAMEWORKS_FOLDER_PATH)/B.framework
$(BUILT_PRODUCTS_DIR)/$(FRAMEWORKS_FOLDER_PATH)/C.framework
This builds fine for me, but when I go to submit to the App Store I get Code signing "A.framework" failed
In the logs I see Running /usr/bin/codesign for
/var/folders/1y/hdyf678f66897f_fafjdkdk89f8d/T/XcodeDistPipeline.7bM/Root/Payload/MyApp.app/Frameworks/A.framework/Frameworks/B.framework/Frameworks/C.framework
And the next line after that same string with a path to C.framework replacing existing signature, then code object is not signed at all on the line after that.
Do I need to specify in my Run Script the path to each sub framework (or in my case sub sub framework)?
I've tried $(SRCROOT)/Carthage/Build/iOS/C.framework/Frameworks/B.framework/Frameworks/C.frameworks, but then it won't compile because it can't find a file at that path (although when I cd to that path it exists).
PS:
B.framework also has a Run Script for C.framework with the same format as the main app
I had a bunch of issues with my project and nested frameworks. I'll list them here:
Only the main app that will be submitted to the App Store should have a Run Script copy-frameworks Phase and it should only copy the top level frameworks.
Only a test target should have a Copy Files Phase (I had a Copy Files phase in my framework target)
Don't embed any frameworks (unless they are static, but those aren't officially supported as of now).
The frameworks shouldn't be code signed themselves (It should be code signed by the main app)
