How to compare two strings ignoring case in Swift language?

Question

How can we compare two strings in swift ignoring case ? for eg :

var a = \"Cash\"
var b = \"cash\"

Is there any method that will return tru

Answer 1

localizedCaseInsensitiveContains : Returns whether the receiver contains a given string by performing a case-insensitive, locale-aware search

if a.localizedCaseInsensitiveContains(b) {
    //returns true if a contains b (case insensitive)
}

Edited:

caseInsensitiveCompare : Returns the result of invoking compare(_:options:) with NSCaseInsensitiveSearch as the only option.

if a.caseInsensitiveCompare(b) == .orderedSame {
    //returns true if a equals b (case insensitive)
}
