Enumeration¶

Edge¶

An enumeration to indicate one edge of a rectangle.¶

Declaration¶

@frozen enum Edge : Int8, CaseIterable

Overview¶

Edge is most frequently used to specify padding with padding(_:), but it can also be returned from instance methods. For example:

struct ExampleView: View {
    var body: some View {
        VStack {
            Text("Example view where Edge is returned as a value")
                .accessibilityScrollAction { edge in
                    switch edge {
                    case Edge.top:
                        print("Swiped down from top edge")
                    case Edge.leading:
                        print("Swiped left from leading edge")
                    case Edge.trailing:
                        print("Swiped right from trailing edge")
                    case Edge.bottom:
                        print("Swiped up from bottom edge")
                    }
                }
        }
    }
}

Note that for illustrative purposes, the enum values were expanded in this example. It would also be valid to use the shorthand, just specifying the values: .top, .leading, .trailing, and .bottom.
