User Profile

Hi. I am trying to make a social media app and I get this problem when I try and download a URL for a post. I am currently following Google's Firebase Documentation. Here is my code.import UIKitimport Firebaseimport FirebaseStorageclass ShareSomethingCell: UITableViewCell { @IBOutlet weak var userImgView: UIImageView! override func awakeFromNib() { super.awakeFromNib() // Initialization code } override func setSelected(_ selected: Bool, animated: Bool) { super.setSelected(selected, animated: animated) // Configure the view for the selected state } func configCell(userImgUrl: String) { let httpsReference = Storage.storage().reference(forUrl: userImgUrl) THIS IS WHERE THE ERROR IS httpsReference.getData(maxSize: 1 * 1024 * 1024) { data, error in if let error = error { // Uh-oh, an error occurred! } else { // Data for "images/island.jpg" is returned let image = UIImage(data: data!) self.userImageView.image = image } } }}
