Adding item to keychain using Swift

Question

Answer 1

This seemed to work fine or at least compiler didn't have kittens - UNTESTED beyond that

        var secret: NSData = "Top Secret".dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion: false)
        var array1 = NSArray(objects:"\(kSecClassGenericPassword)", "MyService", "Some account", secret)
        var array2 = NSArray(objects:"\(kSecClass)","\(kSecAttrService)", "\(kSecAttrAccount)","\(kSecValueData)")
        let query = NSDictionary(objects: array1, forKeys: array2)
        println(query)
        let status  = SecItemAdd(query as CFDictionaryRef, nil)

Seems to work fine in Beta 2
