That's the end of our tour around the Swift programming language. I haven't tried to cover everything in the language, but that's OK because you have all the important stuff, all the sometimes-important stuff, and all the nice-to-know stuff – the many other features you'll either come across in a later project or through extended experience with the language.
From here on, we’re going to focus primarily on building apps. If you want to learn more about the Swift language itself, you might want to consider my Pro Swift book.
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!
