The behavior of onDrag and onDrop in iOS 18 is different from previous versions.

Hwangho, can you please file a feedback with a project or a code snippet that reproduces the issue?

Ok, here is the snippet.

import SwiftUI

struct ContentView: View {  
   @State var str: String = "Drag me"

   var body: some View {
   VStack(spacing: 100) {
  
      Text(str)
       .frame(width: 100, height: 100)
       .background(.blue)
       .onDrag {
          NSItemProvider(object: String(str) as NSString)
       }
  
      VStack {
        Text("Drop Here!")
      }
      .frame(width: 200, height: 200)
      .background(.red)
      .onDrop(of: [.text], delegate: MyDelegate())
   }
  }
}

struct MyDelegate: DropDelegate {
    func performDrop(info: DropInfo) -> Bool {
        return true
    }
}

#Preview {
 ContentView()
}

i'm seeing the same issue - now that I think of it it did start after moving to iOS 18. Has anyone come up with a root cause/approach to solve this?

Have same issue

It is not the only problem. onDrag is re-called even after onDrop is successfully performed. Issue is only on iOS 18

I've reported this issue on FB and this issue will be fixed in 18.1!
