Frequently Asked Questions
How can I report a bug?
If you hit any problems with the app, please let me know and I'll try to get it resolved. Make sure you specify what device you're using as well as which iOS version.
Why wasn't my Free Coding answer accepted?
The Free Coding activity asks you to solve a problem in Swift, and attempts to evaluate whether the code you entered solves the problem or not. Although I've made every effort to make it as thorough as possible, some "creative" solutions might still be marked as wrong. Please let me know and I'll try to fix the app.
What are the points for?
The points and levels help you keep track of your progress.
You earn points for each chapter you read, each test you take, and each practice and challenge you complete. You can share your score with your friends by tapping Share Score on the home page. Unless you're taking a challenge, you get the same number of points regardless of how many mistakes you make – you earn points for trying your best, not for answering everything perfectly. If you want to go back and take a test again to improve your score, go for it!
Can I retake daily challenges?
No; daily challenges can be taken only once a day. Please wait until tomorrow before trying again.
Can I feature Unwrap on my site?
Sure thing! There's a press pack containing screenshots, logos, and a press release with various feature highlights. If you have further requirements just get in touch.
Is the source code for Unwrap available?
Yes! It's available on GitHub at https://github.com/twostraws/Unwrap, so you can see how the app's structured, learn from the code, and – if you want – contribute patches.
