I am having loads of trouble saving each note individually. I used a simple array to hold the notes in ViewController class and retrieved the same array inside DetailViewController as you will see in my code. So far, I've gotten to notes to save but all 4 notes are saving the same text when I want them to be save individually and I think my error is coming from theDidSelectRowAt() method in my viewController Class but I am not totally sure. I think my issue is that I am not saving the textView of each individual note. I don't know how to do that.

here's my ViewController

import UIKit

class ViewController: UITableViewController {
    var notes = ["Note1", "Note2", "Note3", "Note4"]
    override func viewDidLoad() {
        super.viewDidLoad()

    }

    override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return notes.count
    }

    override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        let cell = tableView.dequeueReusableCell(withIdentifier: "Cell", for: indexPath)

        cell.textLabel?.text = notes[indexPath.row]
        return cell
    }

    override func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
        if let vc = storyboard?.instantiateViewController(withIdentifier: "Detail") as? DetailViewController{
            vc.selectedNote = notes[indexPath.row]

          navigationController?.pushViewController(vc, animated: true)
        }

    }

    }

and here's my DetailViewController

import UIKit

class DetailViewController: UIViewController {
    @IBOutlet var textView: UITextView!
    var selectedNote: String?
    var notesTwo = [String]()

    override func viewDidLoad() {
        super.viewDidLoad()
        let otherVC = ViewController()

            notesTwo = otherVC.notes
            //retrieving the text user entered from userDefaults
            let defaults = UserDefaults.standard
            if let noteText = defaults.string(forKey: "noteText"){

                textView.text = noteText
            }

        textView.font = UIFont(name: "Helvetica-Bold", size: 18)

    }

    override func viewWillDisappear(_ animated: Bool) {
        super.viewWillDisappear(animated)

            //saving the text user enters using userDefaults
            if let noteText = textView.text{
                let defaults = UserDefaults.standard
                defaults.set(noteText, forKey: "noteText")
            }
    }

}
