Receiving nil for UIElements inside tableViewCell added via storyboard - ios

Question

I have created a TableViewCell entirely in storyboard just as I have in any other app. I want to set the properties however the components inside of it (such as cellScrollView) are returning nil. They are connected via IBOutlet. I have never had this happen to me before, the line where is error occurs is :
cell.cellScrollView.contentSize = CGSizeMake((2 * cell.frame.size.width), cell.frame.size.height)
And the error is:
fatal error: unexpectedly found nil while unwrapping an Optional value
Below is the ViewController..
import UIKit
class ViewController: UIViewController, UITableViewDataSource {
#IBOutlet weak var scrollView: UIScrollView!
func random() -> CGFloat { return CGFloat(rand()) / CGFloat(RAND_MAX) }
func randomColor() -> UIColor { return UIColor(red: random(), green: random(), blue: random(), alpha: 1.0) }
override func viewDidLoad() {
super.viewDidLoad()
scrollView.contentSize = CGSizeMake(self.view.frame.size.width * 3, self.view.frame.height)
scrollView.contentOffset = CGPoint(x: self.view.frame.size.width, y: 0)
var tableView = UITableView(frame: CGRectMake(self.view.frame.size.width, 0, self.view.frame.size.width, self.view.frame.size.height))
tableView.dataSource = self
tableView.registerClass(SnapchatTableViewCell.self, forCellReuseIdentifier: "cell")
tableView.separatorStyle = UITableViewCellSeparatorStyle.None
scrollView.addSubview(tableView)
// Do any additional setup after loading the view, typically from a nib.
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
//TableView DataSource
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return 80
}
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
var cell = tableView.dequeueReusableCellWithIdentifier("cell", forIndexPath: indexPath) as SnapchatTableViewCell
cell.delegate = self
cell.selectionStyle = UITableViewCellSelectionStyle.None
cell.cellScrollView.contentSize = CGSizeMake((2 * cell.frame.size.width), cell.frame.size.height) //This is where the crash occurs, the error tells me cell.cellScrollView is nil
return cell
}
}
..and here is the class that inherits UITableViewCell and is the custom class of the cell in storyboard:
import UIKit
class SnapchatTableViewCell: UITableViewCell, UIScrollViewDelegate {
#IBOutlet var cellScrollView: UIScrollView!
#IBOutlet var colorView: UIView!
override func awakeFromNib() {
super.awakeFromNib()
// Initialization code
}
override func setSelected(selected: Bool, animated: Bool) {
super.setSelected(selected, animated: animated)
// Configure the view for the selected state
}
//ScrollViewDelegate
func scrollViewDidScroll(scrollView: UIScrollView) {
}
}

Use the viewWithTag() function in the storyboard instead of using outlets.
Give your cellScrollView a tag for example of 100 then simply call cell.viewWithTag(100) as UIScrollView to access your scroll view. Do the same for all subviews in your cell.
