Why doesn't this open when I log in with my Firebase log in? SwiftUI

Question

 Button(action: { signIn() }){ Text("Sign In") .font(.title) .frame(minWidth: 0, maxWidth: 200) .cornerRadius(100.00) .frame(height: 20) .padding() .foregroundColor(.white) .font(.system(size: 14, weight: .bold)) .background(Color.blue) .cornerRadius(5.0) }.alert(isPresented: $showingAlert) { Alert(title: Text(alertTitle), message: Text(error), dismissButton: .default(Text("Ok!"))) }

THE SIGN IN FUNCTION BEING CALLED BELOW! This func and whatnot I think signs me in (I see in my firebase log) but it doesn't transfer me to the next screen. I tried a navlink but it lets you press sign in then go to Home Screen no matter what.

func signIn() {

 if let error = errorCheck() { self.error = error self.showingAlert = true return } AuthService.signIn(email: email, password: password, onSuccess: { (user) in self.clear() }) { (errorMessage) in print("Error \(errorMessage)") self.error = errorMessage self.showingAlert = true return } }

I think what you want is a fullScreenCover. So add a new State variable and add .fullScreenCover(isPresented: $navigate) { YourView()} and in the button where you wanna navigate to the next screen add navigate.toggle(). Let me know if this is what you want — SwiftyJoeyy

add this to your view to activate the next screen;

@State var activate = false

and add this to your view, for example after the button:

NavigationLink("", destination: Text("the next screen"), isActive: $activate)

then add this to your func signIn() just after self.clear() to change the activate state.

activate = true

assuming func signIn() is also in your view.

Note your view must have NavigationView for NavigationLink to work.
