NSRange to Range

Question

How can I convert NSRange to Range in Swift?

I want to use the following UITextFieldDelegate method:

Answer 1

extension StringProtocol where Index == String.Index {

    func nsRange(of string: String) -> NSRange? {
        guard let range = self.range(of: string) else {  return nil }
        return NSRange(range, in: self)
    }
}
