How to add horizontal and vertical scrolling using ScrollView

Paul Hudson    @twostraws   

Updated for Xcode 12.0

SwiftUI’s ScrollView allows us to create scrolling containers of views relatively easily, because it automatically sizes itself to fit the content we place inside it and also automatically adds extra insets to avoid the safe area.

For example, we could create a scroll list of ten text views like this:

ScrollView {
    VStack(spacing: 20) {
        ForEach(0..<10) {
            Text("Item \($0)")
                .foregroundColor(.white)
                .font(.largeTitle)
                .frame(width: 200, height: 200)
                .background(Color.red)
        }
    }
}

Scroll views are vertical by default, but you can control the axis by passing in .horizontal as the first parameter. So, we could flip our previous example to be horizontal like this:

ScrollView(.horizontal) {
    HStack(spacing: 20) {
        ForEach(0..<10) {
            Text("Item \($0)")
                .foregroundColor(.white)
                .font(.largeTitle)
                .frame(width: 200, height: 200)
                .background(Color.red)
        }
    }
}

You can specify both axes at the same time using [.horizontal, .vertical].

Finally, you can decide whether to show the scroll indicators as the scroll action happens, like this:

ScrollView(.horizontal, showsIndicators: false) {
