CryptoSwift test code

ViewController.swift

 
        let key = "1234567890123456" // key
        let iv = "1234567890123456" // random
        let message = textView.text
        let aes = try! AES(key: key, iv: iv)
        
        // encrypt
        let encrypt = try! aes.encrypt(message.dataUsingEncoding(NSUTF8StringEncoding)!.arrayOfBytes(), padding: PKCS7())
        print(encrypt)
        
        let encryptedMessage = NSData(bytes: encrypt).base64EncodedStringWithOptions(NSDataBase64EncodingOptions.Encoding64CharacterLineLength)
        textView.text = encryptedMessage
        
        
        // decrypt
        let dec =  try! aes.decrypt(encrypt, padding: PKCS7())
        let str = NSString(data: NSData.withBytes(dec), encoding: NSUTF8StringEncoding)
        print("revealed message: \(str!)")
        
        //PART 2
        let concelMessgeTest: String = try! "m;alskjdf;alskjf;aslkjdfa;slfkdjas;ldfkjas;ldfjky".encrypt(AES(key: "secret0key000000", iv: "0123456789012345"))
        print("base64: \(concelMessgeTest)")
        //aPf/i9th9iX+vf49eR7PYk2q7S5xmm3jkRLejgzHNJs=   looks good
        
        var textMessage = "\(concelMessgeTest)"
        
        let revealMessgeTest: String = try! textMessage.decrypt(AES(key: "secret0key000000", iv: "0123456789012345"))
        print("reveal: \(revealMessgeTest)")
        // fatal error: Array index out of range
        

Note: I need to figure out how to take encryptedMessage and turn it back into the same format as encrypt on line 8 which is an arrayOfBytes

If you look at line 16. I'm currently using encrypt and not encryptedMessage
