A Swift implementation of Minesweeper.

• MineswifterGame contains the game logic, in functional-ish style (algebraic data types, abuse of functions).
• MineswifterScene contains the view logic—it's a normal SpriteKit scene.
• No drawn sprites—only emoji.

This should run on the simulator or on any device running iOS 7.0+.

To play—tap a square quickly to reveal it, or hold longer to flag it. Hit a bomb, and you die. Uncover all the bomb-less squares and win! Tap the face to start a new game.
