title: Swift Array(string) not working
body: <p>I'm trying to make a hangman game. I'm going to paste my code in because I feel my problem is somewhere in here that I'm just not seeing. Look down and find the part where I wrote THIS IS WHERE THE ERROR OCCURS. Here is the error message I get: Missing argument label 'arrayLiteral' in call. When I add the arrayLiteral the code does not work. I'm very new to Swift so some help would be very appreciated! Thank you! (sorry that there's a lot of code that's probably unrelated to the issue)</p>
