Accessibility traits are a group of attributes on a SwiftUI element. They inform assistive technologies how to interact with the element or present it to your customer. Each element has a selection of default traits, but you might need to change these as you create your UI.

In SwiftUI there are two modifiers to use for traits, .accessibility(addTraits: ) and .accessibility(removeTraits: ) which add or remove traits respectively. Each modifier takes as its argument either a single accessibility trait or a set of traits.
