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.

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?
If your watch app has good VoiceOver support, chances are you'll also have good Assistive Touch support. But an improvement you can make is to implement a quick action (triggered with a double pinch) when there is a main action you can perform.
Toggles or UISwitches are often found separated from the label that precedes (and describes) them; with an unclear label; missing a value, trait, or hint; or even not being actionable at all.
