A UITableView has no variable text, that's why you're seeing the error — Ollie

You have to declare String variable in your 3rd View Controller (Table View Controller) like

var myString: String = ""

override func viewDidLoad() {
    super.viewDidLoad()
}

You can assign value to myString variable from your first view controller like

let DestViewController:tableviewcontroller = segue.destinationViewController as! tableviewcontroller
DestViewController.myString = labelText.text!

And your your tableview view method will be like

override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell
{
    let cell1 = tableView.dequeueReusableCellWithIdentifier("cell1", forIndexPath: indexPath)
    cell1.textLabel!.text = myString
    return cell1
}

The Above is the solution, below i am explaining what was the problem

There is no such text method for UITableview, hence you were getting error at

DestViewController.passdata = tblLable.text! //In first View Controller
cell1.textLabel!.text = tblLable.text! //In second View controller

You need to declare the string variable where you want to use it.

Change it to var passdata : String = "". () parentheses indicate this is class, we just need variable to of type String
