Passing Delegates

[ad_1]

So I must cross knowledge from ThirdVC to FirstVC so principally cross the delegate by way of the second protocol, after which the information by way of the First protocol I am uncertain how I’d do it, that is UIKIT and Storyboard under is what I’ve thus far, it really works however I want it to do what I am asking above.

protocol FirstCall {
    func firstFunction(makerData: String,featuresData: [String])
}

class FirstVC: UIViewController, FirstCall {
    
     var delegate: FirstCall?

    @IBAction func buttonClicked(_ sender: Any) {
        guard let SecondVC = storyboard?.instantiateViewController(identifier: "SecondVC") as? SecondVC else {return}
        SecondVC.delegate = self
        navigationController?.pushViewController(SecondVC, animated: true)
    }
    
    func firstFunction(makerData: String,featuresData: [String]) {
       
        print(makerData)
        print(featuresData)
    }
}


protocol SecondCall {
    func secondFunction(makerData: String,featuresData: [String])
}

class SecondVC: UIViewController, SecondCall {
    
     var delegate: FirstCall?
            
    @IBAction func buttonClicked(_ sender: Any){
        guard let ThirdVC = storyboard?.instantiateViewController(identifier: "ThirdVC") as? ThirdVC else {return}
        ThirdVC.delegate = self
        navigationController?.pushViewController(ThirdVC, animated: true)
    }
    
    func secondFunction(makerData: String,featuresData: [String]){
        delegate?.firstFunction(makerData: makerData,featuresData: featuresData)
    }
}


class ThirdVC: UIViewController {
    
     var delegate: SecondCall?
    
    @IBAction func buttonClicked(_ sender: Any) {
        self.navigationController?.popToRootViewController(animated: true)
        
            delegate?.secondFunction(makerData: makerData,featuresData: featuresData)
        
    }
}
