I have made a simple drag and drop of capsule text item to drop on a Text zone. The targeted Text value is getting the dropped item as text and it changes is value.
The following code works correctly and I am sure it can be useful for beginners who want to perform drag & drop.
The problem I am encountering is that when the draggable item is contained in a Form, then the all form is dragged instead of only the selected item only.
To reproduce it just uncomment the Form { }
Am I missing something or is it really a bug ?
import SwiftUI
import UniformTypeIdentifiers
struct DragView: View {
		var body: some View {
				//Form{
						HStack{
								DropText()
								VStack{
										ForEach((1...10).reversed(), id: \.self) {
												CapsuleText(text: "Test \($0)")
										}
								}
						}
			 // }
		}
}
struct DropText: View {
		@State var myText: String = "Glisser ici"
		@State var targeted: Bool = false
		@State private var onDrag = false
		
		var body: some View {
				VStack{Text(myText)}
						.font(.footnote)
						.padding()
						.foregroundColor(.white)
						.background(targeted ? Color.red : Color.green)
						.clipShape(Capsule())
						.onDrop(of: [UTType.text], delegate: DragRelocateDelegate(dropText: $myText, onDrag: $onDrag))
		}
}
struct CapsuleText: View {
		var text: String
		@State private var onDrag = false
		
		var body: some View {
				VStack{Text(text)}
						.font(.footnote)
						.padding()
						.foregroundColor(.white)
						.background(onDrag ? Color.gray : Color.blue)
						.clipShape(Capsule())
						.onDrag {
								self.onDrag = true
								return NSItemProvider(object: String(text) as NSString)
						}
		}
}
struct DragRelocateDelegate: DropDelegate {
		@Binding var dropText: String
		@Binding var onDrag: Bool
		
		func dropEntered(info: DropInfo) {
		}
		
		func dropUpdated(info: DropInfo) -> DropProposal? {
				return DropProposal(operation: .move)
		}
		
		func performDrop(info: DropInfo) -> Bool {
				guard info.hasItemsConforming(to: [UTType.text]) else {
						return false
				}
				let items = info.itemProviders(for: [UTType.text])
				for item in items {
						_ = item.loadObject(ofClass: String.self) { str, _ in
								if let str = str {
										dropText = str
								}
						}
				}
				return true
		}
}
