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 in this project 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.

If you'd like to make improvements to this project, you could try combining a number of techniques together to make a pretty awesome app.

You're already receiving the URL of the site the user is on, so why not use UserDefaults to save the user's JavaScript for each site? You should convert the URL to a URL object in order to use its host property.

If you wanted to be really fancy, you could let users name their scripts, then select one to load using a UITableView.

SPONSOR Tired of wasting time debugging your Swift app? Instabug’s SDK is here to help you minimize your debugging time by providing you with complete device details, network logs, and reproduction steps with every bug report. All data is attached automatically. It only takes a line of code to setup. Get started for free.

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!
