At the time of writing this post, there are 17 different traits that you can use to define your UI controls. Button, Selected, Not Enabled, Adjustable… are some examples.

More specifically, what I want to look at is not “what APIs are there to help make an app accessible?”, but rather “how do I use the available APIs to make my app accessible as best as possible?”.
Xcode 15 introduces a way of automatically performing accessibility audits on your app through UI tests. Such audits can help you identify accessibility issues such as missing labels for elements, clipped text, insufficient colour contrast, lack of support for Dynamic Type and many more.
