FBSDKLoginManager withReadPermissions error - ios

Question

I am having an issue with converting the value of a UIcollectionViewCell to the argument type of a UIViewController inside my handleCustomFBButton() function below. I believe it is something wrong with setting my delegates and/or datasource...thanks for any and all help!
import UIKit
import FBSDKLoginKit
import Firebase
class LoginCell: UICollectionViewCell, FBSDKLoginButtonDelegate {
let logoImageView: UIImageView = {
let image = UIImage(named: "me")
let imageView = UIImageView(image: image)
return imageView
}()
let emailTextField: LeftPaddedTextField = {
let textField = LeftPaddedTextField()
textField.placeholder = "Enter Email"
textField.layer.borderColor = UIColor.lightGray.cgColor
textField.layer.borderWidth = 1
textField.keyboardType = .emailAddress
return textField
}()
let passwordTextField: LeftPaddedTextField = {
let textField = LeftPaddedTextField()
textField.placeholder = "Enter Password"
textField.layer.borderColor = UIColor.lightGray.cgColor
textField.layer.borderWidth = 1
textField.isSecureTextEntry = true
return textField
}()
lazy var loginButton: UIButton = {
let button = UIButton(type: .system)
button.backgroundColor = .orange
button.setTitle("Log in", for: .normal)
button.setTitleColor(.white, for: .normal)
button.addTarget(self, action: #selector(handleLogin), for: .touchUpInside)
return button
}()
lazy var FBloginButton: UIButton = {
let customButton = UIButton(type: .system)
customButton.backgroundColor = UIColor.blue
customButton.setTitle("Custom button here", for: .normal)
customButton.titleLabel?.font = UIFont.boldSystemFont(ofSize: 16)
customButton.setTitleColor(.white, for: .normal)
return customButton
customButton.addTarget(self, action: #selector(handleCustomFBButton), for: .touchUpInside)
}()
// error happens on the from: self
func handleCustomFBButton() {
FBSDKLoginManager().logIn(withReadPermissions: ["email", "public_profile"], from: self) { (result, err) in
if err != nil {
print("Custom FB Login Button Failed")
return
}
self.showEmailAddress()
}
}
