How to bring NSWindow to front and to the current Space?

I'm using this code to bring up my window:

[self.window makeKeyAndOrderFront:self];
[self.window setOrderedIndex:0];

But often it will be beneath other windows or displayed in other Space desktop that I last open it in. How do I make it always appear "in front" to the user?

Update I found the answer from previously asked question; make the window show up to the top of other windows: [NSApp activateIgnoringOtherApps:YES];

But how to move the app to the user's current Space?

Solution 1:

To bring your app to the front:

[NSApp activateIgnoringOtherApps:YES];

Swift:

NSApp.activateIgnoringOtherApps(true)

Swift 3:

NSApp.activate(ignoringOtherApps: true)

Solution 2:

Perhaps you want:

  [self.window setCollectionBehavior: NSWindowCollectionBehaviorCanJoinAllSpaces];

Experiment with the other collection behaviors... I found NSWindowCollectionBehaviorMoveToActiveSpace was a bit buggy in 10.5 but it might be better now.
