You'll want make sure your ProfileViewController conforms to the UICollectionViewDataSource and UICollectionViewDelegate protocols and when you create the collection view inside the ProfileViewController make sure you do:

collectionView.delegate = self;
collectionView.dataSource = self;

Sounds like you're trying to use self.collectionView, where that property doesn't exist on the ProfileViewController.
