Create object that conform to protocol in Swift

Question

I want to create cell that i know, is conformable to specific protocol.

However, when i try to do :

 func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {

        let cell<ModelBinding> = tableView.dequeueReusableCell(withIdentifier: "VacanciesCell", for: indexPath as IndexPath)

        return cell
    }

I got an error. How to fix it?

you can make an extension to all tableview cell or that specific cell class and conform to that protocol — Lu_

this is extremally easy way, how do you want to make anything easier than that, it conforms or not, that simple — Lu_

let cell : ModelBinding = tableView.dequeueReusableCell(withIdentifier: "VacanciesCell", for: indexPath as IndexPath) as! ModelBinding — Evgeniy Kleban

You have to subclass cell , which confirms the protocol that you want to use. Here i have created a sample protocol and CustomCell which confirming the protocol i have created.

1. Sample protocol

protocol MyProtocol {
    func protocolMethod()

}

2. Custom subClassed cell

class CustomCell:UITableViewCell,MyProtocol {

    //Implementation of Protol method
    func protocolMethod() {

    }

}

3. Use of that cell on tableview

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {

    let cell:CustomCell = tableView.dequeueReusableCell(withIdentifier: "VacanciesCell", for: indexPath as IndexPath) as! CustomCell

    return cell
}
