Grouping elements in SwiftUI is extremely easy! You can use the .accessibility(children: .combine) modifier. And that's it! It merges properties. For example, generating an accessibility label by joining the children's ones, separated by commas.

Sometimes, buttons change meaning, for example when toggled. An example is a play button, tap it and it becomes a pause button. In such case, updating its accessibility label will be clearer than trying to convey the change with traits or values.

Adding keyboard shortcuts in your SwiftUI apps is extremely easy. Just use the .keyboardShortcut(_:) modifier. When pressing and holding the command key, the shortcut will appear in the shortcuts list.
To capture the gesture, you can override the accessibilityPerformEscape() function. In there you can dismiss your view, and return true if you could successfully handle it. https://developer.apple.com/documentation/objectivec/nsobject-swift.class/accessibilityperformescape()
