How to create a custom control for OS X (Swift 2)?

Hello.
I would like to create a user control (containing several standard controls). I find many web pages for iOS, but no for OS X and Swift. Any idea?
Thanks,
Gilbert

What specifically do you want the control to do? OS X is a little different but most of what you learn targeting iOS will be at least useful to you if not directly usable. Have you looked at the OS X Tutorials index? Particularly the first two tutorials on Core Controls might help you get started.
