Print all available font families and font names (Swift)

get-fonts

for family in UIFont.familyNames() {
  let sName: String = family as String
  println("family: \(sName)")

  for name in UIFont.fontNamesForFamilyName(sName) {
    println("name: \(name as String)")
  }
}

In Swift 4 which Xcode 9, the correct syntax is:

for family in UIFont.familyNames {

	let sName: String = family as String
	print("family: \(sName)")
            
	for name in UIFont.fontNames(forFamilyName: sName) {
		print("name: \(name as String)")
	}
}

Running this code leads to a lot warnings in Xcode 13 (and maybe in earlier versions as well):
CoreText note: Client requested name ".SFUI-Regular", it will get TimesNewRomanPSMT rather than the intended font. All system UI font access should be through proper APIs such as CTFontCreateUIFontForLanguage() or +[UIFont systemFontOfSize:]
