How to add drag and drop in SwiftUI

struct SelectFileView: View {
    let buttonTitle: String
    @State var isDrop: Bool = false

    var body: some View {
        VStack(alignment: .leading) {
            Button(action: {}) {
                Text(buttonTitle)
            }
            .buttonStyle(ActionButtonStyle())
            .offset(x: -16)
            Text("Alternatively, you can drag and drop file here")
                .font(.footnote)
                .foregroundColor(Color.gray)
        }
        .border(isDrop ? R.color.separator : Color.clear)
        .onDrop(of: [Constants.urlFileType], delegate: self)
        .padding(.bottom, 32)
    }
}

extension SelectFileView: DropDelegate {
    func dropEntered(info: DropInfo) {
        self.isDrop = true
    }

    func dropExited(info: DropInfo) {
        self.isDrop = false
    }

    func performDrop(info: DropInfo) -> Bool {
        guard
            let itemProvider = info.itemProviders(for: [Constants.urlFileType]).first
        else { return false }

        itemProvider.loadItem(forTypeIdentifier: Constants.urlFileType, options: nil) { item, error in
            guard
                let data = item as? Data,
                let url = URL(dataRepresentation: data, relativeTo: nil)
            else { return }
            
        }

        return true
    }
}
