Cannot Call Value of Non Function Type Swift 3

Question

I am trying to convert my project to swift 3 but get the following error on my code:

Code:

super.collectionView(collectionView, willDisplayCell: cell, forItemAtIndexPath: indexPath)

Error:

Cannot Call Value of Non-function type 'uicollectionview'

Does anyone know the swift 3 edit?

Answer 1

If you are subclassing a UICollectionViewController you should be able to use this:

override func collectionView(_ collectionView: UICollectionView, willDisplay cell: UICollectionViewCell, forItemAt indexPath: IndexPath) {
    super.collectionView(collectionView, willDisplay: cell, forItemAt: indexPath)
}

If you are not subclassing a UICollectionViewController you will likely have to use this:

@objc(collectionView:willDisplayCell:forItemAtIndexPath:) func collectionView(_ collectionView: UICollectionView, willDisplay cell: UICollectionViewCell, forItemAt indexPath: IndexPath) {

}

I have both types of collection views in my apps that I've been updating, and that is what works for me.
