UIFontDescriptor has some strange initializer signatures in the Swift generated header:

    // Instantiation
    init!(fontAttributes attributes: [NSObject : AnyObject]!) -> UIFontDescriptor
    init(name fontName: String, size: CGFloat) -> UIFontDescriptor
    init(name fontName: String, matrix: CGAffineTransform) -> UIFontDescriptor
    // ….
    init!(fontAttributes attributes: [NSObject : AnyObject]?)

Those first three have a return type, which isn’t legal syntax in Swift. It looks to me like this is happening because those inits are bridging UIFontDescriptor factory methods, which have a syntax like:

    + (UIFontDescriptor *)fontDescriptorWithName:(NSString *)fontName

Note that it has a (UIFontDescriptor *) return type instead of the typical (instancetype) — the bridging seems to be tripping up on that. Happily, the initializers still work fine from actual Swift code:

    let descriptor = UIFontDescriptor(name: "Helvetica", size: 16)
