Hacking with Swift Project 14 - Whack-a-Penguin

Build a game using SKCropNode and a sprinkling of Grand Central Dispatch.

It's time for another game, and we'll be using more of SpriteKit to build a whack-a-mole-style game, except with penguins because Whack-a-Penguin isn't trademarked. You're going to learn about SKCropNode, SKTexture and some more types of SKAction, and we'll also use dispatch_after() to execute closures after a delay.
