rangeOfCharacterFromSet(characterSet).location not Swift?

Question

Been going bonkers with this one as all samples I find use the NSRange version but in Swift 2 this method returns a Range so no location to test.

I know that the result of a not found is {NotFound,0} but don't have a scooby doo how to test for it?

if (contact.facebook!.rangeOfCharacterFromSet(characterSet.invertedSet).location != NSNotFound){...}

errors but I cant find out how to query Range

Answer 1

Cast it to a NSString

let objcString = string as NSString

let characterSet = NSCharacterSet.decimalDigitCharacterSet().invertedSet            

if objcString.rangeOfCharacterFromSet(characterSet).location != NSNotFound {
     return false
}
