Remove item from array in UITableview - arrays

Question

What I'm trying to accomplish is when user selects an element for UITableView this element gets append to servicioSeleccionadoarray. But I'm stuck in this because if user decides to deselect the cell I want to remove that item from the array. I've try anyarray.remove(at:)but I can figure the way to tapp into that index.
This is my code so far.
class ServicioHogarViewController: UIViewController{
let serviciosHogar = [String](arrayLiteral: "Alfombras", "Muebles Madera", "Sillones", "Marmol", "Aplicación Teflón","Vestiduras", "Salas", "Colchones", "Sillas Oficinas")
#IBOutlet weak var servicioHogarTB1: UITableView!
var selectedIndex : Int? = nil
var servicioSeleccionado : [String] = []
#IBAction func doneButton(_ sender: UIButton) {
performSegue(withIdentifier: "datePick2", sender: self)
}
override func viewDidLoad() {
super.viewDidLoad()
servicioHogarTB1.delegate = self
servicioHogarTB1.dataSource = self
servicioHogarTB1.register(UINib(nibName: "ServicioHogarCell", bundle: nil), forCellReuseIdentifier: "servicioCell1")
servicioHogarTB1.separatorStyle = .none
}
override func viewWillDisappear(_ animated: Bool) {
super.viewWillDisappear(true)
print(servicioSeleccionado)
}
}
// MARK : UITabeView Delegation
extension ServicioHogarViewController : UITableViewDelegate, UITableViewDataSource{
func numberOfSections(in tableView: UITableView) -> Int {
return 1
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return serviciosHogar.count
}
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
if tableView.cellForRow(at: indexPath)?.accessoryType == .checkmark {
tableView.cellForRow(at: indexPath)?.accessoryType = .none
} else {
tableView.cellForRow(at: indexPath)?.accessoryType = .checkmark
}
if tableView.cellForRow(at: indexPath)?.accessoryType == .checkmark {
servicioSeleccionado.append(serviciosHogar[indexPath.row])
print(servicioSeleccionado)
}
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "servicioCell1", for: indexPath) as! ServicioHogarCell
let servicio = serviciosHogar[indexPath.row]
cell.servicioLabel.text = servicio
return cell
}
}

If you have an array :
var cast = ["Vivien", "Marlon", "Kim", "Karl"]
and you want to remove "Marlon" from it, you can find the index of Marlon using the func firstIndex(of: Element) -> Int? method for an array and then remove it like so :
if let index = cast.firstIndex(of: "Marlon"){
cast.remove(at: index)
print(cast)
}
That said, on didSelectRowAt run this function for your array and you'll accomplish what you're looking to.
