The third challange from HackingWithSwift, 100 days of UIKit (https://www.hackingwithswift.com/100).
Details of the challange can be found here: https://www.hackingwithswift.com/guide/4/3/challenge But in large, the app is a game of Hang Man, where the user is going to guess a letter at a time and have a number of guesses before they lose.
