Ambiguous type name 'Index' in 'Array' PLEASE HELP!!! Mutating the Data Source!!!

For some reason I'm having a problem with the outerIndex and innerIndex declarations. Error "Ambiguous type name 'Index' in 'Array'"..

Apparently there was a typealias keyword used before, however I still getting the same error message.. 

typealias Indexx = Int?
var outIndex: Array.Indexx? = nil

However I still getting the same error message... 
"Ambiguous type name 'index' in Array'"

Any feedback please??

It appears this is mostly abstracted away now. You just need to get the index path then the object itself and update from there.

extension ContactListController: ContactDetailControllerDelegate {
    func didMarkAsFavoriteContact(_ contact: Contact) {
        guard let indexPath = dataSource.indexPath(for: contact) else {
            return
        }

        var favoriteContact = dataSource.object(at: indexPath)
        favoriteContact.isFavorite = true

        dataSource.updateContact(favoriteContact, at: indexPath)
        tableView.reloadData()
    }
}
