I have both Xcode 12.5 and 13 beta4 installed on same machine
after installed 13 beta 4, cannot edit schema-> import GPS on Xcode 12.5. not even when I create a new project with 12.5. the import dialog does appear, however, the gps file are grayed and they cannot be selected with the open/import dialog box.
those gps already installed are also gone and that's how I find out.
again, this is not per project, I tried to create a new projects and hit the same issue.
on the other hand, this feature is ok on the 13 beta 4 side.
