didSelectItemAtIndexPath issue

[Maryom]

Hi,

Thanks for your amazing repo.

I have two issues:

1. I need to implement didSelectItemAtIndexPath so I added it to UserViewController as follow:

func collectionView(collectionView: UICollectionView,
                        didSelectItemAtIndexPath indexPath: NSIndexPath) {
        print("Hi \(indexPath.row)")
    } 

But it doesn't work! Why?

2 . There is a warning: plain style unsupported in a navigation item.

To solve it just change Bar Button Item Style to Bordered as shown in the attached image.
