Solving the Monty Hall Problem in Swift

This is an interesting probability challenge, fondly referred to as the Monty Hall Problem:

“Suppose you’re on a game show, and you’re given the choice of three doors: Behind one door is a car; behind the others, goats. You pick a door, say No. 1, and the host, who knows what’s behind the doors, opens another door, say No. 3, which has a goat. He then says to you, “Do you want to pick door No. 2?” Is it to your advantage to switch your choice?”

Thomas Hanning shows how to solve the problem via a Swift playground.
