For Swift 3.0.1 You can try this:

self.collectionView.selectItem(at: indexPath, animated: true, scrollPosition: [])

or

self.collectionView.selectItem(at: indexPath, animated: true, scrollPosition: UICollectionViewScrollPosition(rawValue: 0))

For Objective-C You can try this:

self.collectionView selectItemAtIndexPath:indexPath animated:YES scrollPosition:UICollectionViewScrollPositionNone];

Note: You should use it in viewDidAppear
