Is there any way to use storyboard and SwiftUI in same iOS Xcode project?

I just started to look at the SwiftUI. Sharing a small example.

1. In the storyboard add Hosting View Controller
2. Subclass the UIHostingController with your own class (ChildHostingController)
3. ChildHostingController should look something like that:

import UIKitimport SwiftUIstruct SecondView: View {  var body: some View {      VStack {          Text("Second View").font(.system(size: 36))          Text("Loaded by SecondView").font(.system(size: 14))      }  }}class ChildHostingController: UIHostingController<SecondView> {    required init?(coder: NSCoder) {        super.init(coder: coder,rootView: SecondView());    }    override func viewDidLoad() {        super.viewDidLoad()    }}

For more details have a look at Custom UIHostingController
Apple Docs UIhostingController (Unfortunatelly it hasn't been documented yet)

Yes you can do that! Here are the steps you can take to do so:

1. Go to your current Xcode project -> Storyboard, click on the + sign (right upper corner) and search for Hosting Controller (just like you would for a button or label).

2. Drag Hosting Controller to your Storyboard. Create a Segue connection from your UI element (I'm using a button) to that Hosting Controller and select Push.Create an outlet connection from that Segue to your View Controller (it's a new feature - just like you would create an outlet for a Label), and name it.

3. Declare your view inside of this outlet connection (you can do that, don't have to use PrepareForSegue method), and return it.

For example: I created a SwiftUI view in my current project (in Xcode: File -> New -> File -> SwiftUI View) and called it DetailsView. My outlet connection would look like this:

import UIKit import SwiftUIclass ViewController: UIViewController {    @IBSegueAction func showDetails(_ coder: NSCoder) -> UIViewController? {        let detailsView = DetailsView()        return UIHostingController(coder: coder, rootView: detailsView)    }    override func viewDidLoad() {        super.viewDidLoad()        // some code    }}

That's it! Now run it.

as Edgell Mentioned, there is a new ViewController named HostViewController that can host a SwiftUI page inside it.there's a complete talk about integrating SwiftUI in existing project at WWDC that answers your question very well.
