CollectionVIew size for item not sets for zero.It displays wrong size swift || sizeForItemAt return 0 but cell came || UICollectionView sizeForItemAt Called But Not Sized Correctly

Problem:

I had tried to set the size for item zero but it not sets properly.For that it returns sized value.

collectionView(_:layout:sizeForItemAt:)

            let newSize =  myArray.count > 0 ? CGSize(width: width/3, height: width/3) : CGSize(width: 0, height: 0)

return newSize

Solution:

Because in apple they already said that you must have to set the size value

to be non zero.

            let newSize =  myArray.count > 0 ? CGSize(width: width/3, height: width/3) : CGSize(width: 0.5, height: 0.5)

return newSize

Use the above code it will works good.
