I created a tableview with swift programmatically. The data is from API. But what i get is cells that are stacked like this :

Here is my code of tableView function:

 override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCell(withIdentifier: "UITableViewCell", for: indexPath)
    cell.selectionStyle = .none
    cell.backgroundColor = .systemBackground
    
    cell.contentView.addSubview(profileUsernameView)
    cell.contentView.addSubview(profilePictureView)
    cell.contentView.addSubview(emailView)
    cell.contentView.addSubview(phoneView)

Anyone can help me so my UITableView's doesn't stacked again? Thank you

First, create a custom UITableViewCell and add the views in it.

class UserCell: UITableViewCell {
    
    private let profileUsernameLabel: UILabel = {
        let label = UILabel()
        label.font = UIFont.systemFont(ofSize: 18, weight: .semibold)
        label.numberOfLines = 0
        label.textAlignment = .left
        label.translatesAutoresizingMaskIntoConstraints = false
        return label
    }()
    
    private let profilePictureView: UIImageView = {
        let imgView = UIImageView()
        imgView.clipsToBounds = true
        imgView.layer.cornerRadius = 45
        imgView.translatesAutoresizingMaskIntoConstraints = false
        return imgView
    }()
