How do I navigate to a View Controller while also using SwiftUI? - ios

Question

I am trying to navigate to a View Controller while currently using NavigationLink from SwiftUI. I am assuming I am not able to do this, so I am wondering how I can navigate to my View Controller in another way while still being able to click on a button from my HomeView and navigate to my ViewController.
Below is my HomeView where I want a button with the text 'Time Sheets' to navigate to my ViewController
struct HomeView: View {
var body: some View {
NavigationView {
VStack {
Image("OELogo")
.resizable()
.frame(width: 400, height: 300)
NavigationLink(destination: ViewController()) {
Text("Time Sheets")
.fontWeight(.bold)
.frame(minWidth: 325, minHeight: 50)
.font(.title)
.foregroundColor(.gray)
.padding()
.overlay(
RoundedRectangle(cornerRadius: 50)
.stroke(Color.gray, lineWidth: 2)
)
}
Below is the start to my code of ViewController file that I want to navigate to
import UIKit
import KVKCalendar
import SwiftUI
final class ViewController: UIViewController {
private var events = [Event]()
private var selectDate: Date = {
let formatter = DateFormatter()
formatter.dateFormat = "dd.MM.yyyy"
return formatter.date(from: "27.7.2020") ?? Date()
}()```

To achieve this, you would need to create a new struct that conforms to UIViewControllerRepresentable. This acts like a wrapper for UIKits UIViewController.
There is a similar protocol for UIView, UIViewRepresentable.
struct YourViewControllerView: UIViewControllerRepresentable {
func makeUIViewController(context: Context) -> ViewController {
// this will work if you are not using Storyboards at all.
return ViewController()
}
func updateUIViewController(_ uiViewController: ViewController, context: Context) {
// update code
}
}
Alternatively, this struct will work if you have your ViewController inside a storyboard.
struct YourViewControllerViewWithStoryboard: UIViewControllerRepresentable {
func makeUIViewController(context: Context) -> ViewController {
guard let viewController = UIStoryboard(name: "Main", bundle: nil).instantiateViewController(identifier: "ViewController") as? ViewController else {
fatalError("ViewController not implemented in storyboard")
}
return viewController
}
func updateUIViewController(_ uiViewController: ViewController, context: Context) {
// update code
}
}
Remember to set the Restoration ID and Storyboard ID in the Interface builder if you are using a storyboard
