Value of type 'string' has no member 'containsString'

Question

I am new to iOS app developing.

I am implementing search bar programatically in swift 3 .

when I updated content for search controller I am getting this error.

value of type 'string' has no member 'containsString'

on this line :

return  categoryMatch &&
 candy.name.lowercaseString.containsString(searchText.lowercaseString)

this is code :

func updateSearchResultsForSearchController(searchController: UISearchController) {
        func filterContentForSearchText(searchText: String, scope: String = "All") {
            filteredCandies = candies.filter { candy in
                let categoryMatch = (scope == "All") || (candy.category == scope)
                return  categoryMatch && candy.name.lowercaseString.containsString(searchText.lowercaseString)
            }

            tableView.reloadData()
        }
    }

Which version of Swift are you talking about?. Please add the information in the question or use appropriate tags. If it's Swift 3 you will get much more errors in this code. — vadian, Mar 15 '17 at 08:08

Read https://swift.org/migration-guide/, don't stay locked in your previous knowledge of Swift. You *have* to keep yourself updated, Swift evolves a lot and often. — Eric Aya, Mar 15 '17 at 10:18

If you're using Swift 3 then change this line

return categoryMatch && candy.name.lowercaseString.containsString(searchText.lowercaseString)

to

return categoryMatch && candy.name.lowercased().contains(searchText.lowercased())

replacing lowercasestrings with lowercased() worked. thanks – santosh naidu Mar 16 '17 at 07:18
**.lowercased()** – J A S K I E R Oct 08 '20 at 22:55
