Sheet modifier on nested view does not work

If a .sheet modifier is used on a child view while the parent view is also using a .sheet modifier, then the child view’s sheet will never appear:

struct ContentView: View {
  @State var isPresented1 = false
  @State var isPresented2 = false

LocalizedStringKey equatable doesn't work as expected

It can be useful to assert again LocalizedStringKey in unit tests. Sometimes there is significant logic that goes into constructing a localized string and so it’s good to be able to write tests against that.

However, as soon as you apply some formatting to a string it seems to break equatability:

LocalizedStringKey("\(1)") == LocalizedStringKey("\(1)") // false

I have found an erroneous invocation of onDisappear in a particular view hierarchy. If you have a NavigationView wrapping a Form, which has a NavigationLink that drills down to a Form, then the inner most Form will have its onDisappear invoked when the view appears.

Here is a code sample that reproduces it:

struct ContentView: View {
  var body: some View {
 NavigationView {

Consider the following code:

class ViewModel: ObservableObject {
  @Published private(set) var value = 0
}

let vm = ViewModel()

struct ContentView: View {
  @State var isFavorite = false

  var body: some View {
    FavoriteComponent(id: 42, isFavorite: self.$isFavorite)
  }
