You want the newest Xcode that has a 10.9 SDK. In my collection of antique Xcodes 6.4 is the latest one, it 
has 10.9 and 10.10. I don't have Xcode 7 or 7.1 and 7.2 has the 10.11 SDK only. There's probably not much 
advantage to moving from Xcode 6.3 to 6.4.

You'll get some improvement by building the latest Gtk (3.24.23) and dependencies, particularly for 
full-screen and the macOS applied tabs.

Note that this list is for supporting developers who build with gtk-osx. It's not a general-purpose Gtk on 
macOS support channel.
