Navigation

Preferred Top Column

Controls which column appears on top of the stack when NavigationSplitView collapses into a single stack in certain contexts, such as on iPhone, when iPhone Duo is closed, or on Apple Watch. By default, the sidebar appears on top. In this case, the detail column does instead.

Explore Preferred Top Column on iPhone in portrait and landscape, with SwiftUI code and Apple API documentation.
