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.

Excellent App

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!

WOW!!! One of the best training apps out there!!!

This is one of the best designed apps out there. If you don’t believe it, TRY IT. I never give app reviews but this one is worth it!!!!!!! It is very well organized and professionally designed. It’s like a very well written book that you just love and can’t put down. Tutorials are short - videos are under 60 seconds, basically you don’t loose interest. You just want to continue studying and little review tests are fun because it checks how well you understand the material that was covered. Thank you Paul! I hope you develop some more similar apps.
