I had a similar problem, this is the hack I came up with.

In your "TestView" declare:

@State var needRefresh: Bool = false

Pass this to your "detailView" destination, such as:

NavigationLink(destination: detailView(feed: self._feed, i: i, needRefresh: self.$needRefresh)) {
     HStack {
            Text(self.feed.items[i].text)
            Text("(\(self.feed.items[i].read.description))")
     }.accentColor(self.needRefresh ? .white : .black)
 }

Note ".accentColor(self.needRefresh ? .white : .black)" to force a refresh when "needRefresh" is changed.

In your "detailView" destination add:

@Binding var needRefresh: Bool

Then in your "detailView" in your Button action, add:

self.needRefresh.toggle()
