Validating Form Field in IOS

Question

I have imported as below:

import SwiftValidator

Below is my ViewController class:

class OriginShipmentViewController: BaseViewController, OriginShipmentView {
     let validator = Validator()
}

You can see that I have initialised validator

Below is the button save click code:

buttonSave?.configureAppearance(
        appearance.mainButtonAppearance, title: localizedKey(key: "origin.next"))
    buttonSave?.addTargetClosure(closure: {_ in
        self.onclickSave()
    })

So you can notice ther is a method call named self.onclickSave() which is as below:

func onclickSave() {
    validator.validate(self)
}

Here, on this line : validator.validate(self) I am getting compile time error as below:

No exact matches in call to instance method 'validate'

What might be the issue? Thanks in advance.

You have not conformed ValidationDelegate yet. By default, this protocol requires two functions validationSuccessful and validationFailed. Try to put these lines of code:

extension OriginShipmentViewController: ValidationDelegate {
    func validationSuccessful() {
        //TODO: 
    }
    
    func validationFailed(_ errors: [(Validatable, ValidationError)]) {
        //TODO: 
    }
}
