Object type looks wrong

[iosware]

You moved dictionary from code into plist file.
But key "code" in plist is now of type Number which you try to assign to NSString. It definitely is wrong.

You are right. This is bad naming convention. However, memory is only allocated during runtime so it doesn't really matter what the object type says in the plist. I will try to see if I can fix it. I'm also open to pull requests fixing this.
