SWIFTUI Binding Not Updating - swiftui

Question

I have a home screen with a “log in” button. Click the button, it will pops up a log in screen. Once it’s logged in, the popover screen will be dismissed. and the home screen will say “logged in!” I have a #State boolean var monitoring button click, and another #EnvironmentObject observing login status. If log in succeeds, isAnon=false . Then the popover window will be dismissed. But it doesn’t work now. when logged in successfully, the popover screen is still on. I’m suspecting the statement Binding<Bool>() doesn’t update when isAnon=false . is this possible ? where did I miss? Thanks a lot! Here is the code
#EnvironmentObject var session: SessionStore
#State var isSignInClicked: Bool = false
var body: some View {
if session.isAnon{// if it is anonymous
Button("Please Sign in to view your activities") {
isSignInClicked.toggle()
}
.popover(isPresented: Binding<Bool>( get: { session.isAnon && isSignInClicked},set: {_ in })){
LogInView()
}
}
else{// if it's logged in
Text("Logged In!")
}
}
}

Answer 1

as #Asperi mentioned, use a #Published for isAnon. This works well for me.
Here is my test code:
import SwiftUI
#main
struct TestApp: App {
#StateObject var session = SessionStore()
var body: some Scene {
WindowGroup {
HomeView().environmentObject(session)
}
}
}
class SessionStore: ObservableObject {
#Published var isAnon = true
}
struct HomeView: View {
#EnvironmentObject var session: SessionStore
#State var isSignInClicked: Bool = false
var body: some View {
if session.isAnon {// if it is anonymous
Button("Please Sign in to view your activities") {
isSignInClicked.toggle()
}
.popover(isPresented: Binding<Bool>( get: { session.isAnon && isSignInClicked},set: {_ in })){
LogInView()
}
}
else {// if it's logged in
Text("Logged In!")
}
}
}
EDIT1: include the missing test LoginView
struct LogInView: View {
#EnvironmentObject var session: SessionStore
var body: some View {
Text("LogInView here")
.onDisappear {
session.isAnon = false
}
// alternative using a button
// Button("LogInView click me") {
// session.isAnon = false
// }
}
}
