The property that the current layout allocates space for its children.
By default, views have a priority of 0, thus distributing space equally among sibling views. However, increasing the view layout priority causes higher-priority views to shrink later when the group shrinks, and to expand faster when the group expands.
HStack {
Text("Life is too short to wait! Start now.")
.background(Color.pink.opacity(0.1))
.layoutPriority(1)
Text("Only in the darkness you can see stars.")
.background(Color.green.opacity(0.1))
