The concept of a "Tab View Bottom Accessory" is discussed in the context of building apps with SwiftUI and UIKit in the WWDC sessions. Specifically, in the session titled "Build a SwiftUI app with the new design," it is mentioned that you can place a view above the bar with the Tab View Bottom accessory modifier. This allows you to take advantage of the extra space provided by the tab bar's collapsing behavior inside your accessory view. You can read the Tab View button accessory placement from the environment and adjust the content of your accessory when it collapses into the Tab bar area.
For more details, you can refer to the session Build a SwiftUI app with the new design (05:35).
