macOS 12.1, Xcode Version 8.1 (8T61a).
App with two windows: FestEvent and Preferences, which have Autosave names of
FestEvent, resp. Preferences.
Start App → FestEvent window will show.
Make it to show Preferences window as well.
Move both windows around and observe Preferences.plist to have absolutely
plausible values for both: “NSWindow Frame Preferences” and: “NSWindow Frame
FestEvent”.
Quit the app.
Start App again → FestEvent window will show, but NOT at its previous location
as recorded in Preferences.plist, but at the location of the Preferences window.
At this second run of my app the following happens:
13:15:49.967892 -[AppDelegate applicationDidFinishLaunching:] Preferences 1030
348 383 83 0 0 1440 877
13:15:49.967929 -[AppDelegate applicationDidFinishLaunching:] FestEvent 0
142 383 247 0 0 1440 877
13:16:06.615131 -[FestWindowController windowDidResize:] FestEvent {{0,
142}, {383, 247}}
13:16:06.639579 -[FestWindowController windowDidLoad] FestEvent {{0,
142}, {383, 247}}
13:16:06.714612 -[AppDelegate applicationDidFinishLaunching:] FestEvent {{0,
142}, {383, 247}}
So far everything is fine: the FestEvent window has the correct location.
But now some obnoxious NSPersistentUIRestorer takes over:
13:16:14.950504 -[FestWindowController windowDidResize:] FestEvent
{{1030, 348}, {383, 83}}
Note: this is the location of the Preferences window.
