How to make a UICollectionView cell touchable/clickable?

Question

I have a UICollectionView with cells that hold images. I would like to make each individual cell of the UICollectionView touchable/clickable through code, how should I approach this?

Answer 1

You need to override the didSelectItemAt: delegate method.

override func collectionView(_ collectionView: UICollectionView, 
             didSelectItemAt indexPath: IndexPath)

Attach the dataSource and delegate for the UICollectionView to your view controller class and implement that method.

In the indexPath parameter, you can get the position of your cell and then perform whatever action you like programmatically. Like pushing a new ViewController etc.
