phone call flow.txt

You've parsed the dictation and determined the user wants to call a contact...

1. Find the Contact
2. Get the Phone Number
3. Actually make the call

--------------------

@IBAction func buttonProcess(sender: AnyObject) {
...
		case "Call":
			resultMessage.text = "Switching to Phone for your call"
      // I'm assuming by this point you have determined that
      //   "actionType" is "Call" and
      //   you have word1 and word2
      makeTheCall()
      break
...
}

var contactToCall: CNContact?
var numberToCall: String?

func makeTheCall() {

  if self.contactToCall == nil {
    
    // find a match

    if matches.count == 0 {
      // no matching contacts... either present a full Contact selection list or abort
      return
    }

    if matches.count > 1 {
      // found multiple matches, so present a list
      pickContact(matches)
      return
    }

    if matches.count == 1 {
      // found ONE matching contact, so go on to get the phone number
      self.contactToCall = matches[0]
    }

  if self.numberToCall == nil {
  
    let numbers = phonesForContact(self.contactToCall)
    
    if numbers.count == 0 {
      // Contact has no phone... show message and abort
      return
    }
