How to add a SearchBar in a TableViewCell programmatically? /Swift - ios

Question

I tried to place a searchBar into the first row of my TableView Cells, but it only throws an error but I don't understand why, can someone tell me what to do? Thanks in advance!
//Custom Cell
class SearchCell: UITableViewCell, UISearchBarDelegate {
let searchbar = UISearchBar()
override init(style: UITableViewCell.CellStyle, reuseIdentifier: String?) {
super.init(style: style, reuseIdentifier: reuseIdentifier)
addSubview(searchbar)
}
required init?(coder: NSCoder) {
fatalError("init(coder:) has not been implemented")
}
func setConstraints() {
searchbar.placeholder = "Country, City"
searchbar.delegate = self
searchbar.searchBarStyle = .minimal
//Constraints
searchbar.translatesAutoresizingMaskIntoConstraints = false
searchbar.centerYAnchor.constraint(equalTo: centerYAnchor).isActive = true
searchbar.leadingAnchor.constraint(equalTo: leadingAnchor, constant: 10).isActive = true
searchbar.widthAnchor.constraint(equalToConstant: 280).isActive = true
searchbar.heightAnchor.constraint(equalToConstant: 40).isActive = true
}
override func awakeFromNib() {
super.awakeFromNib()
setConstraints()
}
override func setSelected(_ selected: Bool, animated: Bool) {
super.setSelected(selected, animated: animated)
// Configure the view for the selected state
}
}
And this is the ViewController which contains the TableView:
class SearchViewController: UIViewController, UITableViewDelegate, UITableViewDataSource, UISearchBarDelegate {
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return 10
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
if indexPath.row == 0 {
!Line 20! let cell = tableView.dequeueReusableCell(withIdentifier: "SearchCell") as! SearchCell
return cell
} else {
let cell = tableView.dequeueReusableCell(withIdentifier: "Cell", for: indexPath)
return cell
}
}
let tableView = UITableView()
override func viewDidLoad() {
super.viewDidLoad()
tableView.dataSource = self
tableView.delegate = self
//
view.backgroundColor = .white
navigationController?.navigationBar.prefersLargeTitles = true
navigationItem.title = "Search"
//Functions
configureTableView()
}
func configureTableView() {
view.addSubview(tableView)
tableView.rowHeight = 80
//Constraints
tableView.translatesAutoresizingMaskIntoConstraints = false
tableView.centerXAnchor.constraint(equalTo: view.centerXAnchor).isActive = true
tableView.centerYAnchor.constraint(equalTo: view.centerYAnchor).isActive = true
tableView.heightAnchor.constraint(equalTo: view.heightAnchor).isActive = true
tableView.widthAnchor.constraint(equalTo: view.widthAnchor).isActive = true
}
}
I watched some tutorials etc. but they didn't help me, so thank you guys!

You need to register your cell with its reuseIdentifier with your tableview first. I don't see that in the code you posted.
After super.viewDidLoad() add something like
tableView.register(SearchCell.self, forCellReuseIdentifier: "SearchCell")
