I have a list of navigation links that I want to be draggable. However, it seems like onDrag conflicts with mouse clicks on macOS (iOS is fine).

Here's some sample code:

Code Block swiftimport SwiftUI
struct ContentView: View {
    var items = ["Peter", "Mark", "Joe", "Frank", "Tim"]
    
    @State var selected: String?
    
    var body: some View {
        NavigationView {
            List {
                ForEach(items, id: \.self) { item in
                    NavigationLink(destination: Text(item), tag: item, selection: $selected, label: {
                        Text(item)
                            .onDrag { () -> NSItemProvider in
                                return NSItemProvider(object: String(item) as NSString)
                            }
                    })
                    
                }
            }
            Text("")
        }
    }
}

Here's the weird part: if you click on the text, the item doesn't get selected and the link seems disabled. However, if you click on a section of the item that is empty, then it works!

Again, this works just fine on iOS. Is this a SwiftUI bug/limitation or am I doing it wrong?

Thanks!

I tested and it works. I can drag (but that does not movve name in the list)

I had just to set the window size to get multiple lines.

Code Block struct ContentView: View {
    var items = ["Peter", "Mark", "Joe", "Frank", "Tim"]
    
    @State var selected: String?
    
    var body: some View {
        GeometryReader { geometry in
            NavigationView {
                List {
                    ForEach(items, id: \.self) { item in
                        NavigationLink(destination: Text(item), tag: item, selection: $selected, label: {
                            Text(item)
                                .onDrag { () -> NSItemProvider in
                                    return NSItemProvider(object: String(item) as NSString)
                                }
                        })
                        
                    }
                }.frame(width: geometry.size.width, height: geometry.size.height)
            }
            Text("")
        }
    }
}
