This updates the app for Swift 5.1, and fixes a bug that caused occasional lines of code to disappear for some users with very small Dynamic Type settings.

Great App for Learning Swift and a Quick Reference
Hacking With Swift's Swift in Sixty Seconds becomes more accessible than ever with Unwrap. Unwrap encourages learning with its leveling system and provides quick access to several topics for those who may be more experienced but need a reminder of how a concept works.
The app is beautifully built with a UI that fits Apple's design pattern, making the user feel like this is a guide Apple's Swift team would want you to use. The Daily Challenges keep users involved and practicing even if they've finished the content. The news section also keeps users updated on the latest from Hacking With Swift without having to leave the app.
Unwrap is a great tool for learning Swift from your phone in a convenient way. This app brings the Hacking With Swift experience to your iPhone in a way that makes it feel like it belongs there.
I’ve been following Paul for a couple years now on my journey to learn Swift. I believe he’s the first resource I found before really diving into it. This is a very good app to learn the Swift language and you’re learning from one of the best in the field. I love the explanations on wrong answers and answers not chosen. I especially love that your progress is saved in your iCloud account so you can switch devices and continue where you left off. There are no ads to annoy and distract you. Paul is very generous for developing this app for free. Another thing I love is that if you email or tweet him with questions or suggestions, he actually answers back. Thank you, Paul for everything you do for us beginner/intermediate Swift developers!
Best way to learn the Swift language, hands-down.
There are a lot of great resources out there for learning the Swift language, but the Unwrap app has been the best one for me! The secret sauce is the review quiz system at the end of each lesson. DON’T SKIP THESE REVIEW QUIZZES. It may sound strange that the review quizzes “teach” you, but try it out and see what I’m talking about.
Also, it’s amazing what you’re getting for free. Videos, quizzes, Dark Mode, iCloud sync, and Split view (to take notes).
I would like to see added: Bookmark a lesson to return to later, share out your review results with answer details (for your tutor), and a macOS (Catalyst) app.
With Family Sharing set up, up to six family members can use this app.
