I want my already logged in users to have my ViewController3 as rootViewController and those who aren't logged in to have ViewController2

Question

Does somebody know which code I should add to my project? The problem I also have is that I use pre-built log in VC, so I am unsure if I can use the same code as those who have built one themselves

Answer 1

Logged Users -> ViewController3 Not Logged Users -> ViewController2

You need to store a value in default user (Core Data / inside the device Phone). Based on this value feed or not you can redirect users proprely :

Add this to your AppDelegate.swift :

    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
    window = UIWindow(frame: UIScreen.main.bounds)
    window = UIWindow(frame: UIScreen.main.bounds) 
    let sb = UIStoryboard(name: "ViewController3", bundle: nil)
    var initialViewController = sb.instantiateViewController(withIdentifier: "Onboarding")
    let userDefaults = UserDefaults.standard
    if userDefaults.bool(forKey: "LoginComplete") {
        initialViewController = sb.instantiateViewController(withIdentifier: "ViewController3")
    }
    window?.rootViewController = initialViewController
    window?.makeKeyAndVisible()

Add this code to your login Viewcontroller3

    override func viewDidLoad() {
    let userDefaults = UserDefaults.standard
    userDefaults.set(true, forKey: "LoginComplete")
    userDefaults.synchronize()

Remove the arrow (initial ViewController) from the mainstoryboard if any This assume that you ViewController2 is the initial VC
