    func getSSID() -> String? {
        let interfaces: CFArray! = CNCopySupportedInterfaces()?.takeRetainedValue()
        if interfaces == nil { return nil }
        
        let if0: UnsafePointer<Void>? = CFArrayGetValueAtIndex(interfaces, 0)
        if if0 == nil { return nil }
        
        let interfaceName: CFStringRef = unsafeBitCast(if0!, CFStringRef.self)
        let dictionary = CNCopyCurrentNetworkInfo(interfaceName)?.takeRetainedValue() as NSDictionary?
        if dictionary == nil { return nil }
        
        return dictionary?[kCNNetworkInfoKeySSID as String] as? String
    }
