Since the "path to application font resources" is now a string type in Xcode 7.3.1, and I could not find a way to use the array for multiple fonts, I used ".". in Info.plist:
Application fonts resource path String .
and it seemed to work to raise all my custom fonts in the Resources folder dynamically, for example. using swift
labelText.font = NSFont(name: "DS-Digital", size: 48)
However, to see it in Xcode design mode (to select a font from the drop-down menu), I had to first add the font to the Font Book.
However, the dynamic method does not require a font book :)
