ScrollView that supports a parallax header image and static overlay

ScrollViewReactiveHeader

A replacement ScrollView that provides a header with subtle scroll animations.

Using ScrollViewReactiveHeader is easy:

ScrollViewReactiveHeader(header: {

    MyHeaderBackground()
        .frame(height: 300)
}, headerOverlay: {

    MyHeaderContent()
        .frame(height: 300)
}, body: {

    // Note: This view will be placed inside a ScrollView
    MyScrollingContentView()
}, configuration: .init(showStatusBar: true, backgroundColor: .white))

Future Todos

  • Make headerOverlay interactive. At the moment, taps will be blocked by the overlaid ScrollView
  • Add optional callback that reports internally-calculated scroll offset.
  • Remove dependency on GeometryReader for calculating status bar height. (at the moment, setting .edgesIgnoringSafeArea(.top) will interfere with this package’s ability to calculate the height of the status bar. )
