Xcode & Swift - Window without title bar but with close, minimize and resize buttons
The new window style mask NSFullSizeContentViewWindowMask added in OS X 10.10 will do the trick.
self.window.titleVisibility = NSWindowTitleVisibility.Hidden;self.window.titlebarAppearsTransparent = YES;self.window.styleMask |= NSFullSizeContentViewWindowMask;
Since MacOS X 10.10, you can use these:
if #available(macOS 10.10, *) { window.titlebarAppearsTransparent = true}if #available(macOS 10.2, *) { window.movableByWindowBackground = true}There was an official sample project for window appearance in Yosemite. You might wanna check it out.
For Swift 3 :-
self.window.titleVisibility = .hiddenself.window.titlebarAppearsTransparent = trueself.window.styleMask.insert(.fullSizeContentView)
