How do I select and highlight a UICollectionView like a UITableViewCell?

I have a simple dilemma. I have a UICollectionViewController in my app that displays saved quizzes. I have the loading right, but I want it to move detect a tap on one of them and then do logic to load it into the main VC. I would like the selection to be similar to a UITableViewCell where it highlights it for a second and then unhighlights it. I am using a subclassed UICollectionViewCell if that helps.

In order for the highlighting to show, you can subclass your cells like this:

import UIKit

class CustomCell: UICollectionViewCell {

    override func awakeFromNib() {
        super.awakeFromNib()

        let backgroundView = UIView(frame: CGRectZero)

        backgroundView.backgroundColor = UIColor.blueColor()

        self.selectedBackgroundView = backgroundView
    }
}

From the docs for UICollectionViewCell:

You can use this view to give the cell a custom appearance when it is selected. When the cell is selected, this view is layered above the backgroundView and behind the contentView.

Unlike UITableView, in UICollectionView there is no specific method defined to do so. U need to implement it programmatically by changing its background colour or background image of the specific cell for instant. U can refer Apple Documentation.https://developer.apple.com/library/ios/documentation/UIKit/Reference/UICollectionView_class/ Hope it helps.

*****EDITED***** You can refer this ans too.. Why UICollectionView's UICollectionViewCell is not highlighting on user touch? Happy Coding.. :)

UICollectionViewCell has a property 

@property(nonatomic, getter=isHighlighted) BOOL highlighted;

You can use this property for selecting the UICollectionViewCell in cellForItemAtIndexPath:
