如何为SwiftUI中的视图更新精确攻丝点处偏移的位置X？

import SwiftUI

struct ContentView: View {
    @State private var offsetX: CGFloat = 0
    
    var body: some View {
        VStack {
            GeometryReader { geometry in
                Text("Hello, SwiftUI!")
                    .font(.largeTitle)
                    .offset(x: self.offsetX, y: 0)
                    .gesture(
                        DragGesture()
                            .onChanged { value in
                                self.offsetX = value.translation.width
                            }
                            .onEnded { value in
                                self.offsetX = 0
                            }
                    )
                    .frame(width: geometry.size.width, height: geometry.size.height)
            }
        }
    }
}

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