swift - 如何将我的按钮定位到屏幕底部？用户界面

Question

下面是我在 SwiftUI 中创建 View 的代码。我要定位我的 欢迎按钮 到屏幕底部，如下所示。

struct welcomeViewControllerView: View {
      var body: some View {
            Text("Welcome")
              .font(.system(size: 20, design: .rounded))
              .padding(.leading)
              .multilineTextAlignment(.center)
              .background(

            Image("splashBackground")
              .resizable()
              .edgesIgnoringSafeArea(.all)
              .frame(width: UIScreen.main.bounds.width, height: UIScreen.main.bounds.height))
        
            Button(action:{print("button pressed")})
              {
                Text("Continue")
                .font(.system(size: 20, design: .rounded))
                .foregroundColor(.black)
                .frame(width: 300, height: 50, alignment: .center)
               .background((Image("buttonImage")).resizable().frame(width: 300, height: 50, alignment: .center))      
         }
      }
   }

class welcomeViewController: UIHostingController<welcomeViewControllerView> {
        required init?(coder: NSCoder)
         {
             super.init(coder: coder,rootView: welcomeViewControllerView());
          }
    
          override func viewDidLoad()
         {
           super.viewDidLoad()
            view.backgroundColor = .white
         }
}

struct ContentView: View {
    var body: some View {
        VStack {
            Image(systemName: "heart.fill")
                .resizable()
                .frame(width: 60, height: 60)
                .foregroundColor(.red)
            
            Group{
                Text("Welcome!")
                    .font(.title)
                
                Button(action: {
                    print("tapped!")
                }, label: {
                    Text("Continue")
                        .foregroundColor(.white)
                        .frame(width: 200, height: 40)
                        .background(Color.green)
                        .cornerRadius(15)
                        .padding()
                })
            }.frame(maxHeight: .infinity, alignment: .bottom)
        }
    }
}

结果:
