This seems to be an issue of iOS 27. If I just use the file app and move a file, the file name is also disabled and the name can't be edited. Can anybody cornfirm this issue? For apps storing a file internally and then exporting it via the files app is this behavior a real desaster.

I usually use the iPhone mini 13 in simulator. I can confirm the behavior. Furthermore the resolution is wrong. Before for "let contentSize = layoutEnvironment.container.effectiveContentSize" you received for contentSize.width -> 375, now you get 320, which is the resolution for the iPhone 5 to SE (first edition). The same is for the height.
