Simple example

import SwiftUI
import SwipingMediaView

struct ContentView: View {
    @State var isPresented: Bool = false
    @State var currentIndex: Int = 1
    var mediaItems: [SwipingMediaItem] = []

    init() {
        self.mediaItems =  [SwipingMediaItem(url: "http://commondatastorage.googleapis.com/gtv-videos-bucket/sample/TearsOfSteel.mp4",
                                             type: .video),
                            SwipingMediaItem(url: "https://i.redd.it/8t6vk567khm91.jpg",
                                             type: .image,
                                             shouldShowDownloadButton: true),
                            SwipingMediaItem(url: "https://i.redd.it/gczavw14bfm91.gif",
                                             type: .gif)]
    }

    var body: some View {
        ZStack {
            Color.green
            VStack() {
                Text(String(currentIndex))
                Spacer()
                Button("Present gallery view") {
                    isPresented = true
                }
            }.padding(100)
        }
        .background(Color.blue)
        // FullScreenCover works well in presenting SwipingMediaView
        .fullScreenCover(isPresented: $isPresented) {
            ZStack{
                SwipingMediaView(mediaItems: mediaItems,
                                 isPresented: $isPresented,
                                 currentIndex: $currentIndex,
                                 startingIndex: currentIndex)
            }
            // Adding a clear background helper here to achieve on drag fading background effect
            .background(BackgroundCleanerView())
            // Ignoring safe area so pinch to zoom don't get cut off
            .ignoresSafeArea(.all)
        }
        .ignoresSafeArea(.all)
    }
}

Example with horizontal scrolled images and on swipe handling

struct ContentView: View {
    @State var isPresented: Bool = false
    @State var currentIndex: Int = 1
    var images: [String] = []
    var mediaItems: [SwipingMediaItem] = []

    init() {
        for i in 0..<64 {
            images.append("https://picsum.photos/250?image=" + String(i))
            mediaItems.append(SwipingMediaItem(url: "https://picsum.photos/250?image=" + String(i),
                                                                                        type: .image,
                                                                                        title: "Image " + String(i)))
        }
    }

    var body: some View {
        ZStack {
            Color.green.opacity(0.5)
            VStack() {
                Text("Current index: " + String(currentIndex))
                Spacer()

            // Horizontal scrolled image view.
            // This is responsible for bringing up the full screen SwipingMediaView.

                                .frame(width: 300, height: 300, alignment: .center)
                                .id(index)
                                .onTapGesture {

                                    isPresented = true
                                }
                        }
                        // Scrolling the view to the image that's being shown on SwipingMediaView
                        .onChange(of: currentIndex) { newIndex in
                            proxy.scrollTo(newIndex, anchor: .top)
                        }
                    }
                }
            }
        }
        // FullScreenCover works well in presenting SwipingMediaView
