fatal error: Unknown AES variant for given key.

[almsx]

Hello,

I am using your code to replicate it within an application that I am developing.

I currently have the following problem:

fatal error: Unknown AES variant for given key.

I have assigned and copied the code as until now you have it in the published github.

I am using version 0.6.9 of CryptoSwift to be compatible with Xcode 8.3.3 and Swift 3.

I attached the code of my ViewController.swift
