gistfile1.m

   // List all fonts on iPhone
    NSArray *familyNames = [[NSArray alloc] initWithArray:[UIFont familyNames]];
    NSArray *fontNames;
    NSInteger indFamily, indFont;
    for (indFamily=0; indFamily<[familyNames count]; ++indFamily)
    {
        NSLog(@"Family name: %@", [familyNames objectAtIndex:indFamily]);
        fontNames = [[NSArray alloc] initWithArray:
                     [UIFont fontNamesForFamilyName:
                      [familyNames objectAtIndex:indFamily]]];
        for (indFont=0; indFont<[fontNames count]; ++indFont)
        {
            NSLog(@"    Font name: %@", [fontNames objectAtIndex:indFont]);
        }
        [fontNames release];
    }
    [familyNames release];

thanks man!

thanks

A more functional approach
var fonts = UIFont.familyNames().map({ UIFont.fontNamesForFamilyName($0)}).reduce([]) { $0 + $1 }

Similar to @TheiOSdeveloper's suggestion, but if you need an Array of UIFonts, you can use this.

func generateFonts(size: CGFloat) -> [UIFont] {
    return UIFont.familyNames().flatMap {
        UIFont.fontNamesForFamilyName($0).flatMap {
            UIFont(name: $0, size: size)
        }
    }
}
