This is breaking because when using the local testing workflow for A-S/rust-components-swift because the local testing workflow updates the Xcode project file to use a local path (file:///) to the rust-components-swift checkout. Since the script you linked only ever looks for https://github.com/mozilla/rust-components-swift, it would always hit the failure case and report that it wasn't added as a dependency, even though it is.
