title: Whenever I add a spacer into my code. it crashes. It works fine until then
body: <p>This is simple code I made to practice with spacers. This is SwiftUI.</p>
  <pre><code>    
      struct Spacer: View {
          var body: some View{
              HStack{
                  Rectangle()
                      .frame(width: 100, height: 100)
                  
                  
                  Rectangle()
                      .fill(Color.red)
                      .frame(width: 100, height: 100)
              }
              .background(Color.blue)
              
          }
      
      }
      
      struct Spacer_Previews: PreviewProvider {
          static var previews: some View {
              Spacer()
          }
      }
