unable to select Item in collection view

Question

I tried to use this code for collectionView How to make a simple collection view with Swift

but for swift 3 I added these changes in viewController

    import UIKit
class ViewController: UIViewController, UICollectionViewDataSource, UICollectionViewDelegate {

    let reuseIdentifier = "cell" // also enter this string as the cell identifier in the storyboard
    var items = ["1", "2", "3", "4", "5", "6", "7", "8", "9", "10", "11", "12", "13", "14", "15", "16", "17", "18", "19", "20", "21", "22", "23", "24", "25", "26", "27", "28", "29", "30", "31", "32", "33", "34", "35", "36", "37", "38", "39", "40", "41", "42", "43", "44", "45", "46", "47", "48"]


    // MARK: - UICollectionViewDataSource protocol

    // tell the collection view how many cells to make
    func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
        return self.items.count
    }

    // make a cell for each cell index path
    func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {

        // get a reference to our storyboard cell
        let cell = collectionView.dequeueReusableCell(withReuseIdentifier: reuseIdentifier, for: indexPath) as! MyCollectionViewCell

        // Use the outlet in our custom class to get a reference to the UILabel in the cell
        cell.myLabel.text = self.items[indexPath.item]
        cell.backgroundColor = UIColor.yellow // make cell more visible in our example project

        return cell
    }

    // MARK: - UICollectionViewDelegate protocol

    func collectionView(collectionView: UICollectionView, didSelectItemAtIndexPath indexPath: IndexPath) {
        // handle tap events
        print("You selected cell #\(indexPath.item)!")
    }
}

It works, but in debug area I am getting this

also when I press any cell nothing happens, I think didSelectItemAtIndexPath not working

@NazmulHasan I fix the method `didSelectItemAt` and its work, but I still have some text in debug area, what this is thing? — joda, Sep 19 '16 at 21:23
@NazmulHasan the header of method was changed in swift 3, I just wrote it again with new style — joda, Sep 20 '16 at 03:05
@joda , No response i think my answers are not compatible with you!. just wanna response for my waste of time! — Rajamohan S, Sep 22 '16 at 16:03

A.didSelectItemAtIndexPath

func collectionView(_ collectionView: UICollectionView, didSelectItemAt indexPath: IndexPath) {
    // handle tap events
    print("You selected cell #\(indexPath.item)!")
}

If you need more about declaring functions then see on Apple Swift 3 documentation.

B.Specify environment variables to disable unwanted logs

go to Product -> Scheme -> Edit Scheme on Xcode Menu.
In the left column, select the Run scheme action.
Click Arguments at the top of the right column.
To add an environment variable, click the Add button (+) at the bottom of the Environment Variables table and enter the variable name as OS_ACTIVITY_MODE and value as DISABLE or disable. Then click close.

If you confused, then see my video.

If you need More about Xcode, then see on apple Xcode Help page.
