Is your SwiftUI view in a NavigationView?
The more I think of it, the more I think my idea is a bad one.
Found this tutorial helpful. Hope it will help you as well.
In your case, I would try doing so:
- declare une unwind segue action in the UIViewController
- in SwiftUI view, create a return button
- connect the return button to the exit icon of the SwiftUI view, and select the unwind.
