DAY 74
Project 15, part 1
We have a new technique project today, this time focusing on something you might not even have considered: accessibility. This is a measure of how well our app can be used by people with varying access needs – they might need larger text, they might need us to avoid certain colors to help them see things clearly, they might need our UI to be read out, and so on.
Too many developers completely ignore the importance of accessibility, which results in apps that are completely opaque to large numbers of people. Tony Fadell – the creator of the iPod at Apple – had this to say: “you are defined by what you do and also by what you don’t do.”
Sure, you can skip accessibility and 90% of people won’t notice, but do you want to be defined by that? I’d wager that the answer is no.
Today you have four topics to work through, in which you’ll learn about accessibility labels, values, hints, and more.
- Accessibility: Introduction
- Identifying views with useful labels
- Hiding and grouping accessibility data
- Reading the value of controls
When you’re done, try using some other apps on your phone with VoiceOver turned on – can you find any that need some improvement?

SPONSORED Let’s face it, SwiftUI previews are limited, slow, and painful. Judo takes a different approach to building visually—think Interface Builder for SwiftUI. Build your interface in a completely visual canvas, then drag and drop into your Xcode project and wire up button clicks to custom code. Download the Mac App and start your free trial today!
