I'm new to Xcode and Swift, and I'm trying to customize my App background, specifically the title bar (as for example the Spotify App does).
So I got it working on Mavericks, but since I installed the Yosemite Beta and the XCode 6 Beta 5, the changes are not applied although there's no code errors whatsoever.
The line I'm using is this:
window.backgroundColor = NSColor(red: 0.12, green: 0.12, blue: 0.12, alpha: 1)
Any ideas?
Cheers, Seb
