Wrap up
I'll tell you what: I'm feeling tired and I didn't even have to learn anything to write this project – I can't imagine how tired you are! But please don't be too disheartened: this project builds the the bridge between JavaScript and Swift, and now that bridge is built you can add your own Swift functionality on top.
Some of the code isn't pleasant to work with, and certainly I wish iOS would just figure out text view insets automatically for keyboards, but you're through it now so your project is done. Even though this was a hard project, I did cut quite a few corners to make the code as easy as possible, so again I want to encourage you to try creating another extension and see how Apple's example code is different from mine.
Review what you learned
Anyone can sit through a tutorial, but it takes actual work to remember what was taught. It’s my job to make sure you take as much from these tutorials as possible, so I’ve prepared a short review to help you check your learning.

Challenge
One of the best ways to learn is to write your own code as often as possible, so here are three ways you should try your new knowledge to make sure you fully understand what’s going on:
- Add a bar button item that lets users select from a handful of prewritten example scripts, shown using a
UIAlertController– at the very least your list should include the example we used in this project. - You're already receiving the URL of the site the user is on, so use
UserDefaultsto save the user's JavaScript for each site. You should convert the URL to aURLobject in order to use itshostproperty. - For something bigger, let users name their scripts, then select one to load using a
UITableView.

Share your success!
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!
