Hacking with Swift Project 26 – Marble Maze

Respond to device tilting by steering a ball around a vortex maze.

In this game project you'll create a rolling ball game for iPad, using the accelerometer – you tip your device, and the balls rolls in that direction, hopefully avoiding holes as you go.

Along with the accelerometer, you're also going to learn how to load levels, how to have fine-grained contact bitmasks, how to reverse arrays, and how to write code that executes in the simulator but not on devices (or vice versa). So, you learn things, you make a cool game, and I get to bask in the warmth of knowing that your Swift mastery is growing more than ever.
