iOS: Extract detected numbers and links from UITextView?

This question and similar ones address how to detect phone numbers and links inside of a UITextView.

Once detected, is there a way to extract the detected numbers and links?

The goal is to use UITextView to detect numbers and links instead of rebuilding this logic.

To clarify, the ideal workflow is:

  1. User enters text into UITextView.
  2. UITextView detects numbers and links.
  3. Extract numbers and links from text.

UITextView really just makes the process of data detection easier to implement for user clickable links. If you are trying to extract and work with that data I would likely recommend implementing it to handle your specific use case. Data detection is luckily very straightforward. 

let string = "www.google.com / (555) 123-4567"

let types: NSTextCheckingResult.CheckingType = [.phoneNumber, .link]
let detector = try NSDataDetector(types: types.rawValue)
let range = NSMakeRange(0, string.count)
detector.enumerateMatches(in: string, options: [], range: range) { result, _, _ in
   print(result)
}

Output: 

Optional(<NSLinkCheckingResult: 0x6000031264c0>{0, 14}{http://www.google.com})
Optional(<NSPhoneNumberCheckingResult: 0x600003f384b0>{17, 14}{(555) 123-4567})
