Search string in an <AnyObject> array with case insensitive

Question

I have an application that stores string values ​​from a server. Then I use SearchView to write a string that may be in the list. It must be case insensitive. While I have it. But this is not the magic I'm looking for.

if (myListTags as NSArray).containsObject(searchBar.text!) {
            print("FOUND")
            getCategoryPick()
}

I tried to join him with help caseInsensitiveCompare, but I failed. Any help for me? It would be great if this code could understand the similarity of letters in Czech .. (č = c, ž = z, í = i ......)

Answer 1

"č" "LATIN SMALL LETTER C WITH CARON". "c" + ", (" CARON ") " ".

(, "č" = "c" ), .DiacriticInsensitiveSearch:

let list = ["č", "ž"]
let search = "C"

if (list.contains {
    $0.compare(search, options: [.DiacriticInsensitiveSearch, .CaseInsensitiveSearch]) == .OrderedSame
    }) {
        print("Found")
} 

, :

if (list.contains {
    $0.rangeOfString(search, options: [.DiacriticInsensitiveSearch, .CaseInsensitiveSearch]) != nil
    }) {
        print("Found")
} 

Answer 2

localizedCaseInsensitiveCompare():

if myListTags.contains({(($0 as? NSString)?.localizedCaseInsensitiveCompare(searchBar.text!) ?? .OrderedAscending) == .OrderedSame }) {
}
