I’m encountering an issue with the autofill behavior in one of my iOS applications. On an action confirmation screen, users can enter a reason in the first text field and their account password in the second text field for validation purpose. However, when users use biometric authentication (Touch ID/Face ID) to autofill the password, the username from the keychain is mistakenly being entered into the reason text field (over-rides the already filled reason).

Here’s the setup:

• The first text field (reasonTextField) is for users to input the reason.
• The second text field (passwordTextField) is for the account password.

I’ve tried the following solutions without success:

1. Setting textContentType to .none for the reasonTextField.
2. Ensuring passwordTextField has textContentType set to .password.
3. Using distinct accessibility identifiers for both text fields.

Here’s a simplified version of my code:

import UIKit

class ActionConfirmationViewController: UIViewController {
    
    @IBOutlet weak var reasonTextField: UITextField!
    @IBOutlet weak var passwordTextField: UITextField!
    
    override func viewDidLoad() {
        super.viewDidLoad()
        
        configureTextFields()
    }
    
    func configureTextFields() {
        reasonTextField.textContentType = .none
        reasonTextField.accessibilityIdentifier = "reasonTextField"
        
        passwordTextField.textContentType = .password
        passwordTextField.accessibilityIdentifier = "passwordTextField"
        passwordTextField.isSecureTextEntry = true
    }
}

Despite these measures, the issue persists. Has anyone experienced a similar problem or have any suggestions on how to prevent the username from being autofilled into the reason text field? Any help would be greatly appreciated!
