in iOS15, refreshable is introduced!

example code struct ContentView: View {   @State private var dragging: Ramen?   @State private var ramens = [Ramen(name: "ramen", id: 0),          Ramen(name: "ramen2", id: 1),          Ramen(name: "ramen3", id: 2)]   var body: some View {     List {       ForEach(ramens) { ramen in         Image(ramen.name)           .onDrag {             self.dragging = ramen             return NSItemProvider(object: String(ramen.id) as NSString)           }       }       .onInsert(of: [.text], perform: insert)     }   }   private func insert(index: Int, _: [NSItemProvider]) {     ...   } }

when dragging

I couldn't figure out how to change it with onInsert, but I did find out that DropProposal is involved. By implementing it with onDrop, I was able to successfully turn it off.

I quit the simulator once and started it again, and it fixed the problem. The cause is unknown.

As far as I can tell, the only way to display the message is to use fatalError.

supplement: repository.delete(id: "2") is doing realm delete transaction. repository.object is getting realm object.

Thank you for your reply！ There is also a difference in the captured image.
