How to pass tableView label to name variable in another viewController? - ios

Question

I'm creating an app for a school project, and I have a tableView with a label inside which contains the name of the cell, and I am trying to pass the name of the label to the navTitle variable on my second viewController. I have tried multiple ways of achieving this but have had no luck.
I have tried printing the passed title but it prints the output 'nil'
Home view
var names = ["Accomodation", "Facilities", "Things To Do", "About"]
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return names.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "homeCell", for: indexPath) as? homeTableViewCell
cell?.label.text = names[indexPath.row]
return cell!
}
//Passing data
var nameChosen : String?
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
self.tableView.deselectRow(at: indexPath, animated: true)
nameChosen = names[indexPath.row]
performSegue(withIdentifier: "accomodationSegue", sender: self)
}
override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
let destinationVC = segue.destination as? accomodationViewController
destinationVC?.navTitle = nameChosen
}
Accomodation view
var navTitle: String?
override func viewDidLoad() {
super.viewDidLoad()
print(navTitle)
// Do any additional setup after loading the view.
}

Answer 1

The easiest way is to pass the name as sender parameter, the property nameChosen is not needed.
And it's good practice to check the identifier of the segue in prepare(for segue
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
self.tableView.deselectRow(at: indexPath, animated: true)
let name = names[indexPath.row]
performSegue(withIdentifier: "accomodationSegue", sender: name)
}
override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
guard segue.identifier == "accomodationSegue" else { return }
let destinationVC = segue.destination as! accomodationViewController
destinationVC.navTitle = sender as! String
}
If the code crashes you made a design mistake.
And please name classes always with starting uppercase letter (AccomodationViewController).
