在顶部有ScrollView的同时使用DragGesture移动视图

import SwiftUI

struct ContentView: View {
    @State private var offset = CGSize.zero
    
    var body: some View {
        VStack {
            ScrollView {
                // ScrollView内容
                VStack {
                    ForEach(0..<10) { index in
                        Text("Item \(index)")
                            .font(.title)
                            .padding()
                            .frame(maxWidth: .infinity)
                            .background(Color.gray)
                            .cornerRadius(10)
                            .padding(.horizontal)
                    }
                }
            }
            .padding(.top, 200) // 设置ScrollView顶部间距，让DragGesture不与ScrollView冲突
            
            Spacer()
        }
        .offset(y: offset.height)
        .gesture(
            DragGesture()
                .onChanged { value in
                    self.offset.height = value.translation.height
                }
                .onEnded { value in
                    self.offset = .zero
                }
        )
    }
}

struct ContentView_Previews: PreviewProvider {
    static var previews: some View {
        ContentView()
    }
}
