Receiver has no segue with identifier "popUpSegue" (Swift 3) - ios

Question

I'm kinda new to swift and i'm having trouble implementing this segue between "ViewController" and "PopUpViewController." I'm trying to pass over an array of quotes between the view but keep getting the "Receiver has no segue with identifier 'popUpSegue' error."
I made absolutely sure that my segue's identifier was written correctly across my code and storyboard, i've done the "product --> clean" resolution proposed on another post, nothing has worked.
Something to note: I'm not performing this segue using a button, I had manually set it from the ViewController storyboard (ctrl-clicked the yellow button on the view controller). I'm not sure if that might have anything to with my issue.
ViewController.swift
import UIKit
class ViewController: UIViewController {
// MARK: Properties
#IBOutlet weak var toucanTut: UIImageView!
#IBOutlet weak var canTooLabel: UILabel!
let quoteArray: NSMutableArray = NSMutableArray()
let tapRecon = UITapGestureRecognizer()
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
tapRecon.addTarget(self, action: #selector(ViewController.tappedView))
toucanTut.isUserInteractionEnabled = true;
toucanTut.addGestureRecognizer(tapRecon)
let urlPath: String = "https://web.njit.edu/~mid6/service.php"
//Retrieves data from DB and handles it
if let url = URL(string: urlPath){
if let data = try? Data(contentsOf: url){
let json = try? JSON(data: data)
//print(json!)
parse(json: json!)
}
}
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
//MARK: Actions
func tappedView(){
let popOverVC = UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: "quotePopUp") as! PopUpViewController
self.addChildViewController(popOverVC)
popOverVC.view.frame = self.view.frame
self.view.addSubview(popOverVC.view)
popOverVC.didMove(toParentViewController: self)
}
func parse(json: JSON) {
for(i , object) in json{
let quote = object["quote"].stringValue
let author = object["author"].stringValue
//print(quote)
let data = IncomingData()
data.quote = quote
data.author = author
quoteArray.add(data)
//print(data)
}
self.performSegue(withIdentifier: "popUpSegue", sender: quoteArray)
}
override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
if segue.identifier == "popUpSegue"
{
if let destinationVC = segue.destination as? PopUpViewController {
destinationVC.newArray = sender as! NSMutableArray
}
}
}
}
PopUpViewController.swift
import UIKit
class PopUpViewController: UIViewController {
//Properties
var feedItems: NSArray = NSArray()
var selectedLocation : IncomingData = IncomingData()
var newArray: NSMutableArray = NSMutableArray()
#IBOutlet weak var quoteText: UILabel!
override func viewDidLoad() {
super.viewDidLoad()
self.view.backgroundColor = UIColor.white.withAlphaComponent(0.8)
checkQuotes()
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
//Actions
#IBAction func closePopUp(_ sender: AnyObject) {
self.view.removeFromSuperview()
}
// check is quoteArray passed over
func checkQuotes(){
print(newArray.count)
}
}

Answer 1

sender The object that you want to use to initiate the segue.
This object is made available for informational purposes during the
actual segue.
Change these lines
self.performSegue(withIdentifier: "popUpSegue", sender: quoteArray)
destinationVC.newArray = sender as! NSMutableArray
To
self.performSegue(withIdentifier: "popUpSegue", sender: self)
destinationVC.newArray = quoteArray
