ScrollRefreshView

SwiftUI ScrollView with Pull to Refresh.

Use UIViewControllerRepresentable wrap UIKit's UIScrollView for SwiftUI. Contains Pull to Refresh feature and scrollViewDidScroll Event.

One regretful thing, the LazyVStack doesn't work in this wrap View. It's not lazy, almost like VStack. :-(

struct ContentView: View {
    
    @State private var isRefreshing = false
    
    func onRefresh() -> Void {
        DispatchQueue.main.asyncAfter(deadline: .now() + 1.5) {
            self.isRefreshing = false
        }
    }
    
    func onScroll(size: CGSize, frame: CGRect, offset: CGPoint) -> Void {
        print("size", size)
        print("frame", frame)
        print("offset", offset)
    }
    
    func onScrollWillEnd() -> Void {
        print("should load more here")
    }
    
    var body: some View {
        ScrollRefreshView($isRefreshing, onRefresh: onRefresh, onScroll: onScroll, onScrollWillEnd: onScrollWillEnd) {
            VStack {
                ForEach(0..<100, id: \.self) { obj in
                    HStack {
                        Text("\(obj)")
                        Spacer()
                    }
                }
            }.background(Color.gray)
        }
        .edgesIgnoringSafeArea(.all)
    }
}
