Building a Tinder-like swipe feature on SwiftUI

I am trying to build a tinder-like swipe feature but I have an issue. All the cards get stacked together on the first screen like in the screenshot below:

It is supposed to look like below

Here is my code:

  MainView

  NavigationView  {
                VStack () {
       
                        ZStack {
                            ForEach(outingsVM.outings, id: \.dateId) { outing in
                                 CardView(outing: outing)
                             }
                         }
                    
                }
               
            }

CardView

 ZStack {
            VStack {
     
     
                HStack {
                        Text("\(outing.name), \(outing.age)")
                }
                .frame(width: 320, alignment: .leading)
                   
                HStack (alignment: .center) {
                    Image(systemName: "figure.walk.circle")
                    Text("\(outing.place)")
                }
                .frame(width: 320, alignment: .leading)
                
                HStack {
                    Image(systemName: "calendar.circle")
                    Text("\(outing.date)  \(outing.time)")
                }
                .frame(width: 320, alignment: .leading)
                
                HStack {
                    Image(systemName: "creditcard.circle")
                    Text("\(outing.payment)")
                }
                .frame(width: 320, alignment: .leading)
          
               // }
                HStack (){
                    Spacer()
                    //accept date
                    Button {
                        showingModal = true
                    } label: {
                        Image(systemName: "checkmark.circle.fill")
                            .font(.system(size: 50))
                            .foregroundColor(.green)
                    }
                    
                    Spacer()
                    
                    //reject date
                    Button {
                        swipeCard(width: -200)
                    } label: {
                        Image(systemName: "xmark.circle.fill")
                            .font(.system(size: 50))
                            .foregroundColor(.red)
                    }
                    
                    Spacer()
                }
                .frame(width: 320)
                .padding()
           }
        }

 

How can I fix this?

>Solution :

You need to add a background to your CardView, e.g.

struct CardView: View {

    var body: some View {
        VStack {
            

        }
        .padding()
        .background(RoundedRectangle(cornerRadius: 8).fill(.white))        
    }
}
