Multiple UILabels on UIViewController

I am trying to control drop two UILabels onto a UIViewController. I keep receiving Cannot override strong property with weak property error.

Here is a short excerpt from my code. Here is a screenshot of all the errors https://gyazo.com/bd97fa42443d12a3aa17a2de55f78b60 

import UIKit

class ViewController: UIViewController {


@IBOutlet private weak var display: UILabel!

@IBOutlet private weak var description: UILabel!

private var userIsInTheMiddleOfTyping = false

@IBAction private func touchDigit(_ sender: UIButton) {
    let digit = sender.currentTitle!
    if (digit == "c") {
        display.text = " "
    } else {
        print("touchDigit \(digit) digit")
        if userIsInTheMiddleOfTyping {
            let textCurrentlyInDisplay = display.text
            if (sender.currentTitle!) == "c" {
                print("it printed c")
                display.text = "sam"

You should declare your UILabels with optional type UILabel? instead UILabel!

You need to rename your description variable since description is the name of a method inherited from NSObject (the base class of UIViewController).
