This is my favorite way of testing VoiceOver. Pick a flow in your app. Turn VoiceOver on. Triple tap with three fingers on the screen to enable Screen Curtain. The screen goes off but you can still navigate your device with VoiceOver.

It is useful to know these VoiceOver gestures to activate/deactivate Screen Curtain, pause/resume VoiceOver, easily simulate a long press for opening context menus, or quickly move the cursor to the screen's first or last elements.
accessibilitySpeechSpellOut asks VoiceOver to speak the sequence of characters. Can be useful for things like promo/reference/authentication codes, phone numbers... it makes more sense to announce each character rather than words and big numbers. Example code in the image: ```swift let codeLabel = UILabel() let attributedLabel = NSAttributedString( string: "BAC1234567D", attributes: [.accessibilitySpeechSpellOut: true] ) title.accessibilityAttributedLabel = attributedLabel ```
Anything representing a heading in the app should have the header trait. It allows for a faster way of exploring a screen and jumping to the part of the app you are interested in. Screens should also start with a header.
