Hey everyone,
How do I detect that my View is coming into the foreground? The app has been suspended by iOS before, because I closed it (which is fine).
I am running into the strange problem, that .onChange(of: scenePhase) is never triggered on my custom subview. It only works if I attach it to the first view inside the root view.
Some context: My app is iOS 17 and iPhone only.
does work: on TabView() inside ContentView()
ContentView() is the root view of the app.
struct ContentView: View {
@Environment(\.scenePhase) var scenePhase
var body: some View {
TabView {
CustomSubView()
}
.onChange(of: scenePhase) { oldPhase, newPhase in
if newPhase == .active {
// some code, does work
} else if newPhase == .background {
// some code, does work
}
}
}
does not work: on CustomSubView() inside TabView() inside ContentView()
struct CustomSubView: View {
@Environment(\.scenePhase) var scenePhaseCustomSubView
var body: some View {
NavigationStack {
}
.onChange(of: scenePhaseCustomSubView) { oldPhase, newPhase in
if newPhase == .active {
// some code, is not firing for some reason -> use onAppear?
}
else if newPhase == .background {
// some code, does work
}
}
}
}
Thank you for your help
