Property 'self.delegate' not initialised at super.init

I am trying to make a protocol in a UITableViewCell class but when i declare my delegate, I get an error in both required init?(coder aDecoder: NSCoder) and override init(style: UITableViewCellStyle, reuseIdentifier: String?)

Error : - Property 'self.delegate' not initialised at super.init

This is my subclass:-

import UIKit

protocol tableCellBtnActionDelegate{

func removeRowAtIndex(_: Int)

}

class FriendsListTableViewCell: UITableViewCell {
@IBOutlet weak var friendListAddBtn: UIButton!
var usersId : String!
var buttonText : String!
var indexPath : Int!
let delegate : tableCellBtnActionDelegate!
override func awakeFromNib() {
    super.awakeFromNib()
    friendListAddBtn.layer.cornerRadius = 4
    friendListAddBtn.layer.backgroundColor = UIColor(red: 121.0/255.0, green: 220.0/255.0, blue: 1, alpha: 1).CGColor
}

required init?(coder aDecoder: NSCoder) {

    super.init(coder: aDecoder)
}
override func setSelected(selected: Bool, animated: Bool) {
    super.setSelected(selected, animated: animated)

}
override init(style: UITableViewCellStyle, reuseIdentifier: String?) {

    super.init(style: style, reuseIdentifier: reuseIdentifier)

}
}

You got a warning because you are not initialising the delegate property. It should actually be a weak property, or you will retain a reference to the delegate object, which you usually don't want to do. So the best approach would be:

weak var delegate : tableCellBtnActionDelegate?

And then you have to use it like this:

self.delegate?.notifyAboutSomething()

Well you haven't initialize it, so the compiler gives you a warning. I would advise you to modify the delegate to be optional and set your delegate whenever you need it.

var delegate : tableCellBtnActionDelegate?

You should also handle the case where delegate is not set(nil).

Change

let delegate : tableCellBtnActionDelegate!

to

var delegate : tableCellBtnActionDelegate!

or you can't set value to delegate property ever
