'ViewController' does not conform to protocol 'ValidationDelegate'

[gauravparvadiya]

Hi,

I have added ValidationDelegate to my viewController and also implementing both required methods. But still, I am getting "Does not conform to protocol" error.

I am using Xcode 9.3 and Swift 4.1

I am using Xcode 12.5, swift 5 faced the same error, but instead of using the

validator.validate(self) and implementing the protocol i used the callback function

validator.validate { [weak self] errors in
    guard let self = self else { return }
    if errors.count > 0 {
        for (field, error) in errors {
            if let field = field as? UITextField {
              field.layer.borderColor = UIColor.red.cgColor
              field.layer.borderWidth = 1.0
            }
            error.errorLabel?.text = error.errorMessage // works if you added labels
            error.errorLabel?.isHidden = false
        }
    } else {
        // success in validation
    }
}
