How To Test Locale In Your Playground in Swift

Today I was preparing a fancy Playground for my talk at Wearables + Things Conference. This is the first time I created a Playground for educational purposes, so naturally I thought it would be super cool to demonstrate how values change based on locale! However, I quickly ran into a problem changing the locale for the entire playground.
