A quick test (in Swift no less) suggests to me that this function just doesn’t work (TM).
I get non-zero results for these 13 flag combinations (count of fonts + mask) and zero results for every other one of the 4096 combinations.
141 NSItalicFontMask
259 NSBoldFontMask
61 NSItalicFontMask + NSBoldFontMask
6 NSExpandedFontMask
3 NSExpandedFontMask + NSBoldFontMask
43 NSCondensedFontMask
12 NSCondensedFontMask + NSItalicFontMask
22 NSCondensedFontMask + NSBoldFontMask
6 NSCondensedFontMask + NSItalicFontMask + NSBoldFontMask
30 NSFixedPitchFontMask
11 NSFixedPitchFontMask + NSItalicFontMask
11 NSFixedPitchFontMask + NSBoldFontMask
5 NSFixedPitchFontMask + NSItalicFontMask + NSBoldFontMask
I think you’re probably better off calling availableFontFamilies then iterating those with availableMembersOfFontFamily: and picking out the ones you want from there. That’s probably better anyway as it will give you all the font families which have both a plain and a bold option which sounds like what you might want. I’d try it out but I’ve exhausted my Swift-fu for the day.
