I have a UITextView with two different hyperlinks in it. To give the chance to choose between the two links when VoiceOver is on, I did:

class MyTextView {
   override func awakeFromNib() {
       super.awakeFromNib()
       let str = "xxxxxx Option 1 yyyy Option 2"
       let attrStr = NSMutableAttributedString(str)
       let rangeOption1 = (str as NSString).range(of: "Option 1")
       let rangeOption2 = (str as NSString).range(of: "Option 2")
       attrStr.addAttributes([.link: "option1", range: rangeOption1])
       attrStr.addAttributes([.link: "option2", range: rangeOption2])

       self.attributedText = attrStr
   }

   override var isAccessibilityElement: Bool {
       get { return true }
       set {}
   }

   override var accessibilityLabel: String? {
       get { return "Link Options" }
       set {}
   }

   override var accessibilityCustomActions: [UIAccessibilityCustomAction]? {
       get {
           return [
                UIAccessibilityCustomAction(name: "Choose Option One", target: self, selector: #selector(option1)),
                UIAccessibilityCustomAction(name: "Choose Option Two", target: self, selector: #selector(option2))]
       }
       set {}
   }

   @objc func option1() { print ("Option 1") }
   @objc func option2() { print ("Option 2") }
}

I did this following this WWDC video from min 33. What I can not manage is that it says Swipe Up or Down to Select a Custom Action, then double tap to activate when the textView is focused.

Right now it says "xxxxxx Option 1 [pause] link [pause] yyyy Option 2 [pause] link [pause]"

Once the textView is focused, if I swipe down on it it tells me the "Choose Option One" and "Choose Option Two". If after it says "Choose Option X" I double tap, the correction option is chosen.

Technically all is good, I just want to to announce the instructions to the user as it does in the video. Worst case scenario I will just append that to the accessibilityLabel, but that's hacky.
