Code:
// // Login.swift // test // // // // // ContentView.swift // test // // // import SwiftUI import FirebaseAuth import FirebaseDatabase struct SignUp: View { @State var Value: String = "" @State var username: String = "" @State var email: String = "" @State var password: String = "" var body: some View { ZStack { LinearGradient(gradient: Gradient(colors: [Color.blue, Color.white]), startPoint: .topLeading, endPoint: .bottomTrailing) .ignoresSafeArea() Rectangle() .fill(Color.white) .frame(width: 300, height: 550) .cornerRadius(10) VStack(spacing: 30){ Image(systemName: "bitcoinsign.circle") .font(.system(size: 70, weight: .medium)) .padding() TextField("Username", text: $username) .frame(width: 200, height: 30) .padding() .overlay(RoundedRectangle(cornerRadius: 10.0).strokeBorder(Color.blue, style: StrokeStyle(lineWidth: 2.0))) .foregroundColor(.green) TextField("Email", text: $email) .frame(width: 200, height: 30) .padding() .overlay(RoundedRectangle(cornerRadius: 10.0).strokeBorder(Color.blue, style: StrokeStyle(lineWidth: 2.0))) .foregroundColor(.green) TextField("Password", text: $password) .frame(width: 200, height: 30) .padding() .overlay(RoundedRectangle(cornerRadius: 10.0).strokeBorder(Color.blue, style: StrokeStyle(lineWidth: 2.0))) .foregroundColor(.green) Button(action: { print("Rounded Button") }, label: { Text("Sign Up") .frame(width: 200, height: 20, alignment: .center) .padding() .background(Color.blue) .foregroundColor(Color.white) .cornerRadius(15) }) } } } struct ContentView_Previews: PreviewProvider { static var previews: some View { SignUp() } } } func signupbuttonpressed(){ createUser(withEmail: email, password: password, username: username) } func createUser(withEmail email: String, password: String, username: String){ Auth.auth().createUser(withEmail: email, password: password) { (result, error) in if let error = error { print("Failed to sign user up", error.localizedDescription) return } else{ guard let uid = result?.user.uid else { return} let values = ["email": email, "username":username] Database.database().reference().child(uid).child("users").updateChildValues(values, withCompletionBlock: { (error, ref) in if let error = error { print("failed to update databse values with error", error.localizedDescription) return } else { print("user successfully created..") } }) } } } When I try call the createUser(withEmail: email, password: password, username: username) function, its says Cannot find 'email' in scope. So my question is how am I able to access @State var username: String = "", @State var email: String = "" @State var password: String = "", in the signupbuttonpressed() function? I am kinda new to swift so I may be missing a simple concept, any help will be appreciated.
