With the button trait VoiceOver will read “button” after the accessibility label and will indicate the user that, when focused, they can double tap anywhere on the screen to interact with it. UIButton has this trait by default.

An interesting speech attribute for attributed accessibility labels is accessibilitySpeechIPANotation that lets you specify how VoiceOver should pronounce a label with the International Phonetic Alphabet (IPA) notation. https://developer.apple.com/documentation/foundation/nsattributedstring/key/accessibilityspeechipanotation
Please, don't use accessibility labels as ids for your UI tests. It can completely ruin the experience for VoiceOver users. There is actually an accessibility identifier property that you can use instead to uniquely identify your UI elements.
Today I want to share something I use a lot. You can convert any article into a “podcast” by enabling Speak Screen in Accessibility Settings, switching to Safari’s Reader Mode and swiping down with two fingers from the top of the screen. I think it is a good example of how if we all knew more about how to use the assistive tech available in iOS, we would find ourselves using more of them, more often, exemplifying quite well that accessibility benefits everyone.
