iOS- Image not showing up with custom cell (Swift)

I'm attempting to use a custom cell class (customCell) to show images from my array in a cell. If I use the default cell (without 'as! customCell') the images show - so I can only assume it is something to do with my custom cell class (customCell)

Here is my custom cell class code:

class customCell: UITableViewCell {

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

var customImageView: UIImageView {
    let customImage = UIImageView()
    customImage.image = UIImage(named: "PlaceholderImage")
    return customImage
}

override init(style: UITableViewCellStyle, reuseIdentifier: String?) {
    super.init(style: .subtitle, reuseIdentifier: reuseIdentifier)

    addSubview(customImageView)

}

required init?(coder aDecoder: NSCoder) {
    fatalError("init(coder:) has not been implemented")
}

}

and my tableView code where I'm attempting to call the image (if it matters):

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

    let array = displayArray[indexPath.section]

    cell.customImageView.image = UIImage(named: "PlaceholderImage")

    if let imageUrl = array.imageUrl {
        let url = URL(string: imageUrl)
        URLSession.shared.dataTask(with: url!) { (data, response, error) in

            if error != nil {
                print(error!)
                return
            }

            DispatchQueue.main.async {

                 cell.customImageView.image = UIImage(data: data!)

            }
            }.resume()
    }

            return cell
}

You need to set the frame of your UIImageView:

var customImageView: UIImageView {
    let customImage = UIImageView()
    customImage.frame = CGRect(x: 0, y: 0, width: self.frame.size.width, height: self.frame.size.height)
    customImage.image = UIImage(named: "PlaceholderImage")
    return customImage
}
