I have a search bar with these data format as a Realm object.

Optional(Results<Place> <0x7fb0d9e0bb10> (

[0] Place {

    name = Federal Street;

    country = United States;

    lat = 42.5447229;

    lon = -71.2809886;

},

...

I'm trying to make the filter working

//MARK: - Search bar methods

extension PlacesVC : UISearchBarDelegate {







    func searchBar(_ searchBar: UISearchBar, textDidChange searchText: String) {



        print("searchText (searchText)")



        places = places.filter { ($0["name"] ?? "").range(of: searchBar.text ?? "", options: [ .caseInsensitive, .diacriticInsensitive ]) != nil }



        if searchBar.text?.count == 0 {



            load()



            DispatchQueue.main.async {

                searchBar.resignFirstResponder()

            }



        }



        table.reloadData()

    }

}

I kept getting

Cannot subscript a value of incorrect or ambiguous type

Any hints on what I did wrong ?

What also should work is if you are using NSPredicate

let bPredicate: NSPredicate = NSPredicate(format: "SELF.name contains[cd] %@", searchText)

places.filter(using: bPredicate)

This is what I did

extension PlacesVC : UISearchBarDelegate {



    func searchBar(_ searchBar: UISearchBar, textDidChange searchText: String) {



        places = places?.filter("name CONTAINS[c] %@", searchBar.text!).sorted(byKeyPath: "name", ascending: true)



        if searchBar.text?.count == 0 {



            load()



            DispatchQueue.main.async {

                searchBar.resignFirstResponder()

            }



        }



        table.reloadData()

    }

}

and it is working perfectly

Hope this will help someone like me in the future.

Filter can be like:

places = places.filter({

                $0

                .name

                .uppercased()

                .components(separatedBy: .whitespaces)

                .filter { $0.hasPrefix(searchText.uppercased())}

                .count > 0

        }).sorted(by: { $0.name > $1.name })
