SwiftUI and UIKit

i saw the way of switch from a View with UIKit to SwiftUI in this video https://developer.apple.com/videos/play/wwdc2019/231

but when running the App on my iPhone crashes, but in the simulator has no error.

My Mac, xcode and iOS are with the beta 2


On My StoryBoard have a View Controller with a button that goes to a Hosting Controller


@IBSegueAction func showDetails(_ coder: NSCoder) -> UIViewController? {
        let rootView = SwiftUIView()
        return UIHostingController(coder: coder, rootView: rootView)
    }


and my SwiftUIView is the basic, just the hello world.

i get the error in the AppDelegate


pointing to:


class AppDelegate: UIResponder, UIApplicationDelegate {


with error: Thread 1: EXC_BAD_ACCESS (code=2, address=0x1026c8180)


am i doing something wrong?
