I have a UI where you can navigate/push views like this: Root view > List of things > View thing > Edit thing
The "Edit thing" view can also delete it. After a delete, I want it to pop back to the "List of things".
Best I've got now is to call `presentationMode.wrappedValue.dismiss()` on the "Edit thing" view, and then again in the "View thing" view, but that time inside DispatchQueue.main.async { }. It works but the double animation is kind of clunky.
Is there a better way?
Looks like that may have to do...

At least/until SUI puts more meat on bones.
hi,
"what KMT said." wait for Swift 2.0.
for what it's worth, perhaps the functionality of View thing > Edit thing could be redesigned into a single View?
i have a simple project that i put out in public (while i am still learning SwiftUI and have no real idea where it will lead) where i have joined these functionalities. there is also a button in the combined View/Edit thing that deletes the object and returns to the list of things.
it uses CoreData for persistence -- which means that some things are a little magical because of the use of @FetchRequest and the fact that CoreData objects are already ObservableObjects -- but the concept is right, i think.
look at h ttps://github.com/DelawareMathGuy/ShoppingList.
***added as an after-thought. your Edit thing could return to your View thing, with edits showing in some obvious fashion, which could then prominently display a "save the changes you made to this View thing" before going back up the navigation stack to your List of things?
hope that helps,

Try NavigationViewKit https://github.com/fatbobman/NavigationViewKit
import NavigationViewKit
NavigationView {
List(0..<10) { _ in
NavigationLink("abc", destination: DetailView())
}
}
.navigationViewManager(for: "nv1", afterBackDo: {print("back to root") })
in any view in NavigationView
@Environment(\.navigationManager) var nvmanager
Button("back to root view") {
nvmanager.wrappedValue.popToRoot(tag:"nv1"){
print("other back")
}
}
You can also call it through NotificationCenter without calling it in the view
let backToRootItem = NavigationViewManager.BackToRootItem(tag: "nv1", animated: false, action: {})
NotificationCenter.default.post(name: .NavigationViewManagerBackToRoot, object: backToRootItem)
