In previous Xcode versions, it was possible to add a folder reference to a project, and in the copy resources build phase it would copy the folder the bundle, rather than the contents (i.e. the folder's contents would be nested inside a directory named after the folder). In Xcode 16.4, when creating a folder reference, the copy resources build phase will copy the contents of the folder to the bundle at the root level (not nested), like the old behavior when creating a group rather than a folder reference. If you look at the raw project.pbxproj file, it shows up as a "File System Synchronized Root Group" rather than a "File Reference". Is there a way to get the old behavior, aside from hand-editing the project.pbxproj file?

I'm currently migrating a midsize (20k LOC) project to Swift structured concurrency. With complete checking turned on, it currently builds with only two warnings, both of which are related to the QLPreviewControllerDelegate protocol: "Main actor-isolated instance method 'previewControllerDidDismiss' cannot be used to satisfy nonisolated protocol requirement; this is an error in the Swift 6 language mode" as well as the same warning but substituting 'previewController(_:transitionViewFor:)' for the method name. I'm confused as to how to make these nonisolated, as they use UIKit classes/subclasses as arguments and/or return types.
