I know that Xcode doesn't have explicit support in the UI for Package Registries yet, but can use packages referenced by ID if the registry is set up through the CLI.
I also see that xcodebuild has support for SCM to registry transformation (resolving and downloading packages through a registry, even if the packages are referenced using their Github URLs) through command line arguments like "-defaultPackageRegistryURL" and "-packageDependencySCMToRegistryTransformation".
Is there any way to achieve the same thing in Xcode itself?
