Issue Description:

import UIKit

class C: NSObject, UICollectionViewDelegate {
    optional internal func indexPathForPreferredFocusedView(in collectionView: UICollectionView) -> IndexPath? {
        return nil
    }
}

<stdin>:5:5: error: 'optional' can only be applied to protocol members
    optional internal func indexPathForPreferredFocusedView(in collectionView: UICollectionView) -> IndexPath? {
    ^

There should be a fix-it to remove the "optional".
