SwiftUI: Infinite Scrolling Horizontal ScrollView

I need to create an infinite horizontal scrolling with ScrollView to scroll a panorama image. So I would like to make this scrolling infinite from both sides, is there any possible way to make it? I have searched maybe using ScrollViewReader can achieve this but no luck.

ScrollView(.horizontal, showsIndicators: false) {


  • Actually for such prepared image it is enough to load it only once, and we need only to Image presenters for it (note: they do not copy memory, but use the same loaded image). Everything else is just about layout on the fly moving current of-screen item depending on drag direction to left or to the right of current one.

    Tested with Xcode 13.4 / iOS 15.5


    Main part of code:

    struct PanoramaView: View {
        let image: UIImage
        private struct Item: Identifiable, Equatable {
            let id = UUID()
            var pos: CGFloat!
        @State private var items = [Item(), Item()]
        // ...
        var body: some View {
            GeometryReader { gp in
                let centerY = gp.size.height / 2
                ForEach($items) { $item in
                    Image(uiImage: image)
                        .resizable().aspectRatio(contentMode: .fill)
                        .position(x: item.pos ?? 0, y: centerY)
                        .offset(x: dragOffset)
            .background(GeometryReader {
                Color.clear.preference(key: ViewSizeKey.self,
                                       value: $0.frame(in: .local).size)
            .onPreferenceChange(ViewSizeKey.self) {

    and usage

        let panorama = UIImage(contentsOfFile: Bundle.main.path(forResource: "panorama", ofType: "jpeg")!)!
        var body: some View {
            PanoramaView(image: panorama)
                .frame(height: 300)   // to demo of dynamic internal layout
