Issue Description:
Attempting to compile the code below produces the message "failed to produce diagnostic for expression; please submit a bug report (https://swift.org/contributing/#reporting-bugs) and include the project" (so I must obey).
import SwiftUI
struct ContentView: View
{
// The message occurs next to the line below in Xcode:
var body: some View {
NavigationView {
List {
// Had a ForEach here
}
.navigationTitle("Things")
.toolbar {
EditButton()
// Commenting out the ToolbarItem line and its
// closing brace makes the message go away.
ToolbarItem(placement:.navigationBarLeading) {
Button("Add") {
// do nothing
}
}
}
}
}
}
