How to place a UISwitch in an UITableViewCell accessoryView?

Question

I would like to place an UISwitch in a accessoryView of a UITableViewCell, the problem is that if I try to place it right in the cellForRowAtIndexPath func it works and the UISwitch is correctly created and displayed at the right of the UITableViewCell, instead if I create it outside of the func it won't work. I need to create it outsite of the fun because I need to check the status of the UISwitch in some other func and execute code accordingly.

I explain better what I mean for "outside": with Objective-C you have @property(ies) that lets you access objects from everywhere inside the current class file, can we achieve the same thing in Swift?

This is my code:

import UIKit

class ConfigurationViewController: UITableViewController, UITextFieldDelegate {
    weak var useAuthenticationSwitch: UISwitch!

    override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
        let cell = tableView.dequeueReusableCellWithIdentifier("reuseIdentifier", forIndexPath: indexPath) as! UITableViewCell

        if indexPath.section == 0 {
            if indexPath.row == 0 {
                cell.textLabel!.text = "Use Authentication"
                cell.accessoryView = useAuthenticationSwitch
            }
        } else {

        }

        return cell
    }
}

If, instead of:

cell.accessoryView = useAuthenticationSwitch

I use:

cell.accessoryView = UISwitch()

It works

Answer 1

You are not creating the UISwitch.

Replace this:

weak var useAuthenticationSwitch: UISwitch!

With this:

var useAuthenticationSwitch = UISwitch()

Hope this helps.
