When building custom components, or if not relying on UIControl's attributes to configure state, it can be easy to forget to specify the right accessibility traits. These are indispensable for a good experience with VoiceOver, Switch Control...

When using VoiceOver on a device without a home button it can first be confusing how you can do a few things, including going to Home from an app, or opening the App Switcher, Control Center, or Notifications. Here's a quick guide for you.
Do you know when a UI element is greyed out to show that it is disabled? Yes, there is an accessibility trait for that too: .notEnabled. VoiceOver will say “dimmed” after its accessibility label and Voice Control and Switch Control will skip it.
In Objective-C accessibility traits are a bitmask. Some devs find tricky to work with them using bitwise operations. In Swift they conform to the OptionSet protocol that conforms to SetAlgebra. That means you can simply insert/remove traits.
