Avoid Index Out Of Range error in swift

In my UICollectionView I'm trying to return 1 item, if there's no data (in order to set an empty cell then).
Here is the code:

var movies = [Movies]()


func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int
if movies.count == 0
return 1
else
return movies.count




I'm getting Fatal Error: Index Out Of Range. I know, that this way I'm trying to access an element under index[1] and that's impossible, because that element doesn't exist, that's the reason of this error.

But how can I avoid it in this case?

movies.count

As of you are returning 1 count in numberOfItemsInSection for empty array you need to check that your array is empty or not in cellForItemAt before subscripting with it.

1

numberOfItemsInSection

cellForItemAt

func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell
if movies.isEmpty
//return your empty cell

else
//access array element and return cell




return movies.count == 0 ? emptyCell : cell
