the error I'm receiving that I can't seem to fix is
Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'Could not find a storyboard named 'MainTabController' in bundle NSBundle
the app will build and the login screen will display but crashes immediately after with the error stated above.
I have tried all of the following from other post similar to this and have had no luck.
- Removing the reference to the storyboard in the info.plist file. When I do this the app does start but I get a black screen as it doesn't load the storyboard.
- Fiddle with the Target Membership Main.storyboard.
- Remove the storyboard from the project, clean, run and then adding the storyboard back again.
- Uninstall Xcode, reinstall Xcode.
- Deleting the Derived Data folder.
the problem appears to be with my presentMainScreen() method
func presentMainScreen(){
let mainstoryboard = UIStoryboard(name: "MainTabController", bundle: nil)
let mainTabController = mainstoryboard.instantiateViewController(withIdentifier: "MainTabController") as! MainTabController
mainTabController.selectedViewController = mainTabController.viewControllers?[1]
//let storyboard:UIStoryboard = UIStoryboard(name:"Main", bundle:nil)
//let loggedInVC:LoggedInVC = storyboard.instantiateViewController(withIdentifier: "LoggedInVC") as! LoggedInVC
//self.present(loggedInVC, animated: true, completion: nil)
}
if I comment out the mainTabController lines the app will work perfectly, also if I uncomment the loggedInVC lines and with the mainTabController lines commented out it works perfectly as well.
any suggestions are greatly appreciated.
below is my entire ViewController.swift code and a screenshot of my workspace
ViewController.swift
import UIKit
import FirebaseAuth
class ViewController: UIViewController {
@IBOutlet weak var emailTextField: UITextField!
@IBOutlet weak var passwordTextField: UITextField!
override func viewDidLoad() {
super.viewDidLoad()
}
override func viewDidAppear(_ animated: Bool) {
if Auth.auth().currentUser != nil {
print("success")
self.presentMainScreen()
}
}
@IBAction func creatAccountTapped(_ sender: Any) {
if let email = emailTextField.text, let password = passwordTextField.text {
Auth.auth().createUser(withEmail: email, password: password, completion:{ user, error in
if let firebaseError = error {
print(firebaseError.localizedDescription)
return
}
print("success")
self.presentMainScreen()
})
}
}
@IBAction func loginButtonTapped(_ sender: Any) {
if let email = emailTextField.text, let password = passwordTextField.text {
Auth.auth().signIn(withEmail: email, password: password, completion: { (user, error) in
if let firebaseError = error {
print(firebaseError.localizedDescription)
return
}
print("success")
self.presentMainScreen()
})
}
}
func presentMainScreen(){
let mainstoryboard = UIStoryboard(name: "MainTabController", bundle: nil)
let mainTabController = mainstoryboard.instantiateViewController(withIdentifier: "MainTabController") as! MainTabController
mainTabController.selectedViewController = mainTabController.viewControllers?[1]
//let storyboard:UIStoryboard = UIStoryboard(name:"Main", bundle:nil)
//let loggedInVC:LoggedInVC = storyboard.instantiateViewController(withIdentifier: "LoggedInVC") as! LoggedInVC
//self.present(loggedInVC, animated: true, completion: nil)
}
}
What is the name of your storyboard? Is it MainTabController.storyboard or Main.storyboard?
You are trying to load a storyboard named "MainTabController":
let mainstoryboard = UIStoryboard(name: "MainTabController", bundle: nil)
But previously you called it Main.storyboard:
Fiddle with the Target Membership Main.storyboard.
Also if the main tab controller is in the same storyboard as your login view controller then you can try to use this:
let mainTabController = self.storyboard.instantiateViewController(withIdentifier: "MainTabController")
Your story board is named as Main.storyboard. MainTabController is the controller in the Main storyboard.
let mainstoryboard = UIStoryboard(name: "Main", bundle: nil)
let mainTabController = mainstoryboard.instantiateViewController(withIdentifier: "MainTabController") as! MainTabController
mainTabController.selectedViewController = mainTabController.viewControllers?[1]
let mainstoryboard = UIStoryboard(name: "MainTabController", bundle: nil)
Your storyboard is named "Main"
