Phone number validation using NSDataDetector

How can I validate phone number using NSDataDetector. In my project, the anything higher than 14 text length is also valid but NSDataDetector does not detect it that way.

I am using the code from the following stackoverflow post: NSTextCheckingResult for phone numbers

Use NSDataDetector for regular phone numbers, and add a special regex matching only 14-digit+ phone numbers that your app needs to add the missing results. For shorter phone numbers, NSDataDetector will be far more accurate that any regex you may write...

you can't use NSDataDetector its available in for only [10_7,4_0]

enter image description here

So its easy and proper way to validate Phone Number Like bellow way instead of NSDataDetector

    NSString *string =@"121453315"; 
    NSString *phoneRegex = @"^((\\+)|(00))[0-9]{6,14}$";
    NSPredicate *phoneTest = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", phoneRegex];
    BOOL phoneValidates = [phoneTest evaluateWithObject:string];
