This is What it looks like Table View is in
I am using Firebase for Authentication, when I logout and Login again to the app with the account, I get this error.
This is my TabBarViewController (UITabBarController)
import UIKit
class TabBarViewController: UITabBarController {
override func viewDidLoad() {
super.viewDidLoad()
setUpScreens()
}
private func setUpScreens() {
guard let currentEmail = UserDefaults.standard.string(forKey: "email") else { return }
let home = HomeScreen()
home.title = "Home"
let profile = ProfileScreen(currentEmail: currentEmail)
profile.title = "Profile"
home.navigationItem.largeTitleDisplayMode = .always
profile.navigationItem.largeTitleDisplayMode = .always
let nav1 = UINavigationController(rootViewController: home)
let nav2 = UINavigationController(rootViewController: profile)
nav1.navigationBar.prefersLargeTitles = true
nav2.navigationBar.prefersLargeTitles = true
nav1.tabBarItem = UITabBarItem(title: "Home", image: UIImage(systemName: "house"), tag: 1)
nav2.tabBarItem = UITabBarItem(title: "Profile", image: UIImage(systemName: "person"), tag: 2)
setViewControllers([nav1, nav2 ], animated: true)
}
}
This is my Profile Screen where the tableview is present

How can I solve this Problem?
My Xcode version is 14.3.x My Swift version is 5.8.1
I have tried
- to create another account to login
- Change the TableView's Background Color
- Remove and add tableView Again
- Uninstall and install the app again
- Erase simulator data
- Clean the build folder with ( Shift + cmd + K )
