# navigationTitle(_:)

Configures the view’s title for purposes of navigation,

## Discussion

A view’s navigation title is used to visually display
the current navigation state of an interface.
On iOS and watchOS, when a view is navigated to inside
of a navigation view, that view’s title is displayed
in the navigation bar. On iPadOS, the primary destination’s
navigation title is reflected as the window’s title in the
App Switcher. Similarly on macOS, the primary destination’s title
is used as the window title in the titlebar, Windows menu
and Mission Control.

Refer to the <doc:Configure-Your-Apps-Navigation-Titles> article
for more information on navigation title modifiers.
