Adding search bar to filter the uicollection View

I am following this tutorial .The program execution stops 

 override func viewDidLoad() {
        super.viewDidLoad()

        collectionView.delegate=self /////error line 
        collectionView.dataSource=self /////error line

        self.searchController.searchResultsUpdater = self
        self.searchController.delegate = self
        self.searchController.searchBar.delegate = self

        self.searchController.hidesNavigationBarDuringPresentation = false
        self.searchController.dimsBackgroundDuringPresentation = true
        self.searchController.obscuresBackgroundDuringPresentation = false
        searchController.searchBar.placeholder = "Search for tools and resources"
        searchController.searchBar.sizeToFit()

        searchController.searchBar.becomeFirstResponder()

        self.navigationItem.titleView = searchController.searchBar



        // Do any additional setup after loading the view, typically from a nib.
    }

the program execution stop at these two lines 

 collectionView.delegate=self /////error line 
collectionView.dataSource=self /////error line

The error is

Your collectionView outlet have not been connected with the UICollectionView from Storyboard, Connect them, and then it will work.
