With Carthage 0.38.0 developers will be able to download XCFrameworks as prebuilt assets from Github. Then we can integrate Braintree via Carthage again. Could you please verify if this could could be an option to re-support Carthage?

This would be a big advantage since Braintree is huge and takes some time to re-download when we have to delete Xcode's DerivedData folder (Carthage dependencies can be cached much easier than SPM dependencies).

To give some context, this is what I do to archive my frameworks as XCFrameork which can be uploaded to GitHub:
