Once you learn some basic gestures with VoiceOver, it is very important to master he Rotor. It is very useful to also know some more power user gestures like the Magic Tap or the Escape gesture.

VoiceOver will traverse elements from left-right, and from top-bottom. If for any reason you need to change that order, in SwiftUI you can change the accessibility sort priority. A higher priority number in the container means it will go first.
Meet the rotor. A menu that you activate (and change options) by rotating two fingers on the screen. It lets you select different navigation modes and customizations. Like navigating through headings or changing VoiceOver’s speaking rate.
When implementing a UISlider, it is a good idea to consider how much the slider value should change when swiping up/down to adjust it. It might not always make sense to do it in 10% increments, which is the default behaviour. Could be because the value at those intervals doesn't make sense, or feel random, or because it wouldn't provide the user with a fine enough control being able to go through the whole slider in just 10 swipes. It user will still be able to adjust the slider to any value by double tapping and holding and then moving the finger left or right, bypassing VoiceOver gestures. VoiceOver announces the new value as it changes.
