Issue description

When performing a distribution build (‘archive’ configuration in Xcode), exporting fails on bitcode verification in CardinalMobile.framework. It looks like it contains i386 symbols in the binary.

Presumably there should be a step to strip these out of the CardinalMobile framework. We’re currently using Carthage for builds. I’m thinking this should be handled by the copy-frameworks script step of Carthage.

But, adding $(SRCROOT)/Carthage/Build/iOS/BraintreePaymentFlow.framework/CardinalMobile.framework to Carthage copy-frameworks input file list, and $(BUILT_PRODUCTS_DIR)/$(FRAMEWORKS_FOLDER_PATH)/CardinalMobile.framework to the output files list does not fix the issue.

Is this possibly an issue in the bitcode configuration in the way the upstream CardinalMobile.framework has been built?
