When interacting with a button with VoiceOver, the accessibility label is repeated to the user. If you are playing some audio, it could be difficult to listen to it properly. To avoid that, you can add the .startsMediaSession accessibility trait.

There is another accessibility trait: .playsSound, that does a similar thing than .startsMediaSession. This one seems more suitable for buttons that have their own sound effects when interacting with them, like it often happens in games.
This is a small trick I use to compose complex accessibility labels/values when, for a UI component, some elements might not be in all its instances. An array of optional Strings, compact map, and join all elements by a separator, like a comma.
With the attribute accessibilitySpeechPunctuation, you can ask VoiceOver to speak any punctuation marks in your attributed accessibility label, if that is what you want. Good for code snippets?
