Use of unresolved identifier 'FUIEmailAuth'FUIEmailAuth - swift

Question

I'm making a login screen using firebase auth UI and swift.
When I run the app, currently it only shows a welcome screen like this welcome screen.
But I want to display the page the firebase prebuilt UI with a text field that a user can type their email address, something like this. login-with email
Here is my current code.
import UIKit
import FirebaseUI
class ViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
}
//MARK: - sign in / sign up
#IBAction func playPressed(_ sender: UIButton) {
let authUI = FUIAuth.defaultAuthUI()
guard authUI != nil else {
return
}
authUI?.delegate = self
authUI?.providers = [FUIEmailAuth()]
let authViewController = authUI!.authViewController()
present(authViewController, animated: true, completion: nil)
}
}
extension ViewController: FUIAuthDelegate{
func authUI(_ authUI: FUIAuth, didSignInWith authDataResult: AuthDataResult?, error: Error?) {
if error != nil {
return
}
performSegue(withIdentifier: K.loginSegue, sender: self)
}
}
and I get error on the code written as "authUI?.providers = [FUIEmailAuth()]". The error message is
Use of unresolved identifier 'FUIEmailAuth'FUIEmailAuth
I saw some other people run into the same problem, and I tried pod update, but I still get the error message.
Also, on the firebase document, they use 'FUIEmailAuth' in their sample code, so I wonder why I'm getting that error and how to fix it.

Answer 1

I just add pod 'FirebaseUI/Email' in my pod file and it solved the problem.
