The SwiftUI TabView container provides a mechanism via which the user can navigate between content views by selecting tabs in a tab bar or, when using the page view style, making swiping motions. When using the tab bar, the TabView is implemented by declaring child content views and assigning a tab item to each view. The tab items appear in the tab bar and can be constructed from a Text view, an Image view or a combination of Text and Image views.
To control the current selection of a TabView programmatically, each tab item must be assigned a tag containing a unique value, binding the TabView current selection value to a state property.
