give tableviewcell buttons different colors according to index. this did not work neither in WilldisplayCellAt nor at the CellForROwAt level

This code works fine ONLY when i sroll through my table view but the first cell that loads and appear are not taking the needed colors. I tried to call the func in CellforRowAt and CellWillDisplayAt and both had the same effect

And what is driving me crazy is that the backgroundview takes the colors correctly, But the Button title color only takes effect for the first cells upon scrolling and the code of view and button are implemented in same func

The class extensions where i load my cell from a XIB file

extension MyPlansTableViewCellPresenter : UITableViewDataSource {

func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    return items.count
}

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCell(withIdentifier: identifier, for: indexPath) as! MyPlansTableViewCell
    return cell
}

func tableView(_ tableView: UITableView, willDisplay cell: UITableViewCell, forRowAt indexPath: IndexPath) {
    let newcell = cell as! MyPlansTableViewCell
    newcell.setCellColors(index: indexPath.row)
    //This code works fine ONLY when i sroll through my table view but the first cell that loads and appear are not taking the needed colors. 
}
}

My cell is designed in a XIB file and loaded there and here is the Class of it

class MyPlansTableViewCell: UITableViewCell {

@IBOutlet weak var renewBtn: UIButton!
@IBOutlet weak var upgradePlanBtn: UIButton!

override func awakeFromNib() {
    super.awakeFromNib()
    // Initialization code
}

override func layoutSubviews() {
    super.layoutSubviews()
}

override func setSelected(_ selected: Bool, animated: Bool) {
    super.setSelected(selected, animated: animated)
}


public func setCellColors(index: Int){
    if index % 2 == 0 {
        upgradePlanBtn.titleLabel?.textColor = .TextColor
        holderView.backgroundColor = .TextColor
    } else if index % 2 == 1 {
        upgradePlanBtn.titleLabel?.textColor = .systemYellow
        holderView.backgroundColor = .systemYellow
    }
}

This is what i want to achieve, My codes works well only after scrolling but to overcome the first cells that appear on launch

try this !!

public func setCellColors(index: Int){
if index % 2 == 0 {
    upgradePlanBtn.setTitleColor(.TextColor, for: .normal)
    holderView.backgroundColor = .TextColor
} else if index % 2 == 1 {
    upgradePlanBtn.setTitleColor(.systemYellow, for: .normal)
    holderView.backgroundColor = .systemYellow
}

You have to specify the state of the button in the code using this code

upgradePlanBtn.setTitleColor(.systemYellow, for: .normal)

It will work if you set color inside draw function

override func draw(_ rect: CGRect) {
    super.draw(rect)

    //Your code here
}
