Hi all,

I have been trying to add SwiftUI content to my existing UIKit apps, and I seem to be either missing or understanding something. Here's what I have so far:

When an end user taps a top-right navigation button (help) i'd like the SwiftUI view controller to come up.

1. I am initializing the UIHostingController according to the WWDC Video, and am getting NO errors.

2. I've added a UIHostingController to the storyboard and made connections according to the video, no errors.

3. When I run the app and go to the SwiftUI view controller, the app hangs.

What am I missing?

Thanks,

Dan Uff

Can you stop the app in the debugger and get a stack backtrace? Also, if you could post a small code sample showing how you're presenting your view, and how the SwiftUI view is designed (is it just a collection of static views, or are there callback modifiers like .didAppear() involved, for instance?) that would be really useful.
