I've enjoyed making this project, so I hope you enjoyed following along. Plus you have yet more Swift coding experience under your belt, now complete with
follow(), color blending and, yes, even the shake gesture – although I wouldn't be surprised if you switch to having a button on the screen to make explosions easier!
There's a lot more you can do with this foundation behind you. How about adding a score label? Or perhaps adding different fireworks spread types, for example one where fireworks launch from the left and right?
Or if you fancy a bigger challenge, how about making the game end after a certain number of launches? You will need to use the
invalidate() method of
Timer to stop it from repeating.

One of the most effective motivators of success is sharing your progress with other people – when you tell folks what you're doing and what you've learned, it encourages you to come back for more, which in turn will help you reach your app development goals faster.
So, now that you've done all the hard work it's time to share your success: tell folks that you've completed this project, either by clicking the button below to start composing a tweet, or by writing your own message from scratch. This will definitely encourage you to keep learning, but it will also help other folks discover my work – thank you!
