title: Why is the label's text not updating?
body: <p>I'm trying to pass data forward from a table view cell button to a view controller. Depending on which row the button is selected in I want the following view controller label's text to be set accordingly. However, when I try to do so, my labels in the following view controller stay blank and don't change. How can I change this?</p>
  
  <p>I added an action to <code>tipButton</code> in a table view controller that creates segue to the <code>KeysController</code> FYI.</p>
  
  <p>Code for table view cell:</p>
  
  <pre><code>class DrillsTableViewCell: UITableViewCell {
  
  var videoURL:[URL] = [URL(fileURLWithPath: "/Users/RalphSimmonds/Desktop/plainjayne/coolinDB/cook.mov"), URL(fileURLWithPath: "/Users/RalphSimmonds/Desktop/plainjayne/coolinDB/check.MOV")]
  var video = URL(fileURLWithPath: String())
  var initialRow = Int()
  var firstTips = ["Tip 1: Stay Hydrated", "Tip 1: Keep elbow tucked", "x", "Tip 1: Take quick breaks:", "Tip 1: Keep your head up", "Tip 1: Don't cross your feet", "Tip 1: Don't do more than 15 reps"]
  
  var player: AVPlayer?
  var playerController = AVPlayerViewController()
  
  @IBOutlet weak var drillTitle: UILabel!
  @IBOutlet weak var tipButton: UIButton!
  @IBAction func tipsButton(_ sender: UIButton) {
      print(String(initialRow))
  
      let tipsVC = UIStoryboard(name: "main", bundle: nil).instantiateViewController(withIdentifier: "KeysController") as! KeysController
      tipsVC.key1.text = firstTips[initialRow]
  }
  </code></pre>
  
  <p>Code for the view controller whose labels I'm trying to update:</p>
  
  <pre><code>import UIKit
  
  class KeysController: UIViewController {
      @IBOutlet weak var topLabel: UILabel!
      @IBOutlet weak var key1: UILabel!
  
      override func viewDidLoad() {
          super.viewDidLoad()
      }
  }
  </code></pre>
