Drag&Drop doesn't work

Im making an app that uses drag&drop but, it doesn't work. This is made with Swift Playground. If you can find a solution, please let me know. Here is the code.

    //MARK: Drop Area
    @ViewBuilder
    func DropAera()->some View{
        VStack(spacing: 12){
            ForEach($rows,id:\.self){$row in
                HStack(spacing: 10){
                    ForEach($row){$item in
                        
                        Text(item.value)
                            .font(.system(size: item.fontSize))
                            .padding(.vertical,5)
                            .padding(.horizontal,item.padding)
                            .opacity(item.isShowing ? 1 : 0)
                            .background{
                                RoundedRectangle(cornerRadius: 6, style: .continuous)
                                    .fill(item.isShowing ? .clear : .gray.opacity(0.25))
                            }
                            .background{
                                // If Item is Dropped into Correct Plase
                                RoundedRectangle(cornerRadius: 6, style: .continuous)
                                    .stroke(.gray)
                                    .opacity(item.isShowing ? 1 : 0)
                            }
                        // MARK: Adding Drop Operation
                        // MARK: Adding Drag Drop Operation
                            .onDrop(of: [.url], isTargeted: .constant(false)) {
                                providers in
                                
                                if let first = providers.first{
                                    let _ = first.loadObject(ofClass: URL.self) {
                                        value,error in
                                        
                                        guard let url = value else{return}
                                        if item.id == "\(url)"{
                                            droppedCount += 1
                                            let progress = (droppedCount / CGFloat(characters.count))
                                            withAnimation{
                                                item.isShowing = true
                                                updateShuffledArray(character: item)
                                                self.progress = progress
                                            }
                                        }
                                        else{
                                            //Animating When Wrong text
                                            animateView()
                                        }
                                        
                                        
                                    }
                                }
                                
                                return false
                            }
                    }
                }
                
                
                if rows.last != row{
                    Divider()
                }
                
            }
        }
    }
    
    @ViewBuilder
    func DragArea()->some View{
        VStack(spacing: 12){
            ForEach(shuffledRows,id: \.self){row in
                HStack(spacing: 10){
                    ForEach(row){item in
                        
                        Text(item.value)
                            .font(.system(size: item.fontSize))
                            .padding(.vertical,5)
                            .padding(.horizontal,item.padding)
                            .background{
                                RoundedRectangle(cornerRadius: 6, style: .continuous)
                                    .stroke(.gray)
                            }
                        // MARK: Adding Drag Drop Operation
                            .onDrag{
                                // Returning ID to find whitch Item is Moving
                                return .init(contentsOf: URL(string: item.id))!
                            }
                        
                        
                            .opacity(item.isShowing ? 0 : 1)
                            .background{
                                RoundedRectangle(cornerRadius: 6, style: .continuous)
                                    .fill(item.isShowing ? .gray.opacity(0.25) : .clear)
                            }

                         
                        
                    }
                }
                if shuffledRows.last != row{
                    Divider()
                }
                
            }
        }
        
    }

For me, I think some thing is wrong with "url" part. The result shows the id doesn't matches.(probably)

Drag&Drop doesn't work
