Unwind segue not unwinding - ios

Question

I'm trying to create a simple unwind segue but apparently I've made a mistake somewhere. The save button I would like to unwind reacts to pressing but doesn't unwind to the table view. Thanks in advance I appreciate it.
import UIKit
class NoteTableViewController: UITableViewController {
var notes = [Note]()
override func viewDidLoad() {
super.viewDidLoad()
// Uncomment the following line to preserve selection between presentations
// self.clearsSelectionOnViewWillAppear = false
// Uncomment the following line to display an Edit button in the navigation bar for this view controller.
// self.navigationItem.rightBarButtonItem = self.editButtonItem()
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
// MARK: - Table view data source
override func numberOfSections(in tableView: UITableView) -> Int {
// #warning Incomplete implementation, return the number of sections
return 0
}
override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
// #warning Incomplete implementation, return the number of rows
return 0
}
override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "reuseIdentifier", for: indexPath)
return cell
}
//ACTION
#IBAction func unwindToNoteList(sender: UIStoryboardSegue) {
if let sourceViewController = sender.source as? ViewController, let noteTaken = sourceViewController.noteTaken {
// Add a new meal.
let newIndexPath = IndexPath(row: notes.count, section: 0)
notes.append(noteTaken)
tableView.insertRows(at: [newIndexPath], with: .automatic)
}
}
}
and my view controller
import UIKit
import os.log
class ViewController: UIViewController, UITextFieldDelegate {
#IBOutlet weak var typeField: UITextField!
#IBOutlet weak var textDisplay: UILabel!
#IBOutlet weak var saveButton: UIBarButtonItem!
var noteTaken: Note?
func textFieldDidEndEditing(_ textField: UITextField) {
textDisplay.text = typeField.text
}
func textFieldShouldReturn(_ textField: UITextField) -> Bool {
// Hide the keyboard.
typeField.resignFirstResponder()
return true
}
override func viewDidLoad() {
super.viewDidLoad()
typeField.delegate = self
// Do any additional setup after loading the view, typically from a nib.
}
//NAV
override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
super.prepare(for: segue, sender: sender)
// Configure the destination view controller only when the save button is pressed.
guard let button = sender as? UIBarButtonItem, button === saveButton else {
os_log("The save button was not pressed, cancelling", log: OSLog.default, type: .debug)
return
}
let note = typeField.text ?? ""
// Set the meal to be passed to MealTableViewController after the unwind segue.
noteTaken = Note(note: note)
}
#IBAction func cancelButton(_ sender: UIBarButtonItem) {
dismiss(animated: true, completion: nil)
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
}

Answer 1

This is how I create my unwind segues:
Write the code for the unwind segue in the first View Controller:
#IBAction func unwindSegue(Segue: UIStoryboardSegue) {
// Run code when the view loads up
}
Create the segue in main.storyboard:
Give the segue an identifier:
then call it in code:
#IBAction func UnwindButton(_ sender: UIButton) {
performSegue(withIdentifier: "UnwindSegue", sender: UIButton())
}
Hope this helps!!!
