How to get indexpath from row index Swift

Question

I am loading an array to UIcollectionview(later will add other data) . I want to select collection view item randomly as:

var indexpath = Int(arc4random_uniform(UInt32(items.count)-1) 

self.collectionview.selectitem(at: **indexpath**, animated:true ,scrollPosition:UICollectionViewScrollPosition)

Here it’s giving me error at bold position saying:

cannot convert value of type Int to expected argument type 'IndexPath?

I can understand this exception as indexpath is different in swift from collection data index(array index). But I am unable to find any method that can convert item index to indexpath or anyother way.

I am newer to iOS so might be not good at searching correct keywords for such issue. It will be a great favour from you all for any other method to this requirement.

Swift 4.1. Here I created function to get NSIndexPath. Just pass your UIView(UIButton,UITextField etc) and UICollectionView object to get NSIndexPath.

func getIndexPathFor(view: UIView, collectionView: UICollectionView) -> NSIndexPath? {

        let point = collectionView.convert(view.bounds.origin, from: view)
        let indexPath = collectionView.indexPathForItem(at: point)
        return indexPath as NSIndexPath?
    }
