Convert a Universal (FAT) Framework to an XCFramework

Background Strava consumes various third party frameworks via Carthage to power our application. These frameworks are either built from an Xcode project stored in a Github repository (Carthage’s github directive in the Cartfile) or distributed as prebuilt artifacts (Carthage’s binary directive in the Cartfile). The binary dependencies are typically distributed as…
