Accessibility: Wrap up

Paul Hudson    @twostraws    December 8th 2019

Accessibility isn’t something that’s “nice to have” – it should be regarded as a fundamental part of your application design, and considered from the very beginning onwards. SwiftUI didn’t get its excellent accessibility support because Apple thought about it at the last minute, but instead because it got baked in from the start – every part of SwiftUI was crafted with accessibility in mind, and we’d be doing a great disservice to our users if we didn’t match that same standard.

What’s more, I hope you can agree that adding extra accessibility is surprisingly easy – some special values here, a little grouping there, and some bonus traits are all simple things that take only minutes to add, but are the difference between “opaque” and “easy to use” for millions of people around the world.

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 extending this app to make sure you fully understand what’s going on.

1. The check out view in Cupcake Corner uses an image that doesn’t add anything to the UI, so find a way to make the screenreader not read it out.
2. Fix the steppers in BetterRest so that they read out useful information when the user adjusts their values.
3. Do a full accessibility review of Moonshot – what changes do you need to make so that it’s fully accessible?
