'How can NSAttributedString in iOS 15 have " no member 'rtf' "?

According to Apple Documentation, from iOS 3.2, NSAttributedString has a method rtf, defined as:

    var attrText : NSAttributedString = textView.attributedText!
    var docAttr  = [NSAttributedString.DocumentAttributeKey : Any]()
    let rtfData = attrText.rtf(
          from: NSMakeRange(0, attrText.length), 
          documentAttributes: docAttr)
    print(String(data: rtfData, encoding: .utf8) ?? "no data")

However, in my iOS 15 class (which imports UIKit), in XCode 13.2, when I try to access the method XCode warns me "Value of type 'NSAttributedString' has no member 'rtf'.

What's going on?
