title: Why is there a "plus" icon at the top right corner of my view?
body: <p>I'm trying to implement the drag and drop feature to my <code>LazyHGridview</code>. When I try to drop the view on another view, a &quot;plus&quot; icon within a green circle is displayed at the top right corner of the view.</p>

  <pre><code>struct TestView: View {
  var d: GridData
    @Binding var list: [GridData]
    @State private var dragOver = false
     
    var body: some View {
      VStack {
        Text(String(d.id))
          .font(.headline)
          .foregroundColor(.white)
      }
      .frame(width: 160, height: 240)
      .background(colorPalette[d.id])
      .onDrag {
        let item = NSItemProvider(object: String(d.id) as NSString)
        item.suggestedName = String(d.id)
        return item
      }
      .onDrop(of: [UTType.text], isTargeted: $dragOver) { providers in
         
        return true
      }
      .border(Color(UIColor.label), width: dragOver ? 8 : 0)
    }
  }
  }
