The .selected accessibility trait indicates when an element has been selected. You’ll notice that VoiceOver announces “selected” before the accessibility label. You can find that in the system for the selected tab in the tab bar, for example.

Very often we need to show a UISwitch preceded with a UILabel that explains what it does. The text in the label is basically the accessibility label for the switch. Ideally we want for both components to be grouped behave as a UISwitch. It makes much easier to understand what the switch does, compared to having two separate accessible components. There is a number of ways you can do that. One of them is to use a container view and proxy the switch accessibility attributes.
Have you noticed that the first time you select an element on Apple Podcast's mini player, VoiceOver says "Mini player", and then, it describes the selected element? It gives the user more context on what "feature" those elements belong to. This can be achieved in UIKit by configuring the accessibility container type of the mini player with .semanticGroup and giving it an accessibility label, in this case: "Mini player". https://developer.apple.com/documentation/objectivec/nsobject-swift.class/accessibilitycontainertype https://developer.apple.com/documentation/uikit/uiaccessibilitycontainertype/semanticgroup
