Ambiguous type name 'Index' in 'Array' PLEASE HELP!!! Mutating the Data Source | Introduction to Table Views

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

I have been looking around, but apparently there's no answer or good explanation for it.

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

var outIndex: Array.Index? = nil

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

Hi Christian,

I could do with a link to the course you're doing but have you tried .index rather than .Index? i.e. no capitalisation.

Steve.

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()
    }
}
