Present view from UIViewRepresentable in SwiftUI

Question

I just created a UIKit tableView with UIViewRepresentable .

Now I need to present a new SwiftUI View, if a tableCell is selected.

This is what I've done so far:

struct UIKitTableView: UIViewRepresentable {

    @Binding var showDetail: Bool

func makeCoordinator() -> Coordinator {
    Coordinator(showDetail: self.$showDetail)
}

class Coordinator: NSObject, UITableViewDataSource, UITableViewDelegate {

    @Binding var showDetail: Bool

    /// Did select row at
    func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
        self.showDetail = true
    }

Now in my SwiftUI view I can present the view with:

NavigationLink(destination: CellDetail(), isActive: self.$showDetail) {

But I also need to pass the data of the corrispective cell, and I was wondering which is the best approach.

My other question is: Is the @Binding showDetail approach correct? How can I improve my solution?

According to the situation, you're describing I don't understand why you would need to use UIViewRepresentable , since SwiftUI already have a very good implementation of it under the name of List

Here is a piece of code to help you show detail view:

import SwiftUI

struct MasterView: View {
    private let cells = [
        "Cell 1", "Cell 2", "Cell 3"
    ]

    var body: some View {
        NavigationView {
            List(cells, id: \.self) { cell in
                NavigationLink(destination: DetailsView(content: cell)) { // Creates all the logic to show detail view.
                    Text(cell)
                }
            }.navigationBarTitle("List")
        }
    }
}

struct DetailsView: View {
    let content: String

    var body: some View {
        VStack {
            Text(content)
                .font(.largeTitle)
        }
    }
}

Keep in mind that UIViewRepresentable only helps when a view isn't implemented yet in SwiftUI.
