Example default dialer project

I'm trying to create a dialer app for iOS that will make verified cellular, not voip, calls by registering the calls on my server with an option for passphrase offline verification. This means that I want to build a dialer with a nice UX, so I'm trying to use the new default dialer capability.

I've read https://developer.apple.com/documentation/livecommunicationkit/preparing-your-app-to-be-the-default-dialer-app which links to https://developer.apple.com/documentation/livecommunicationkit/startcellularconversationaction for starting a call, but when I try to actually use it in my app it says "Cannot find type 'TelephonyConversationManager' in scope" and similar, despite importing LiveCommunicationKit.

Is there a default dialer example app & xcode project I can look at for how this should be set up?

As I understood it I should be able to use these from iOS 18.2, and I'm targeting that version in my project. The page for StartCellularConversationAction says Beta 26.0 though, have I misunderstood something? does some flag need to be set in my xcode to be able to use this?

I read that all test devices need to be in the EU, that should not be the problem.

I don’t know much about this framework, but the docs for TelephonyConversationManager make it clear that it’s new in iOS 26 beta. That means:

You need to build with Xcode 26 beta.
Your app will either need to require iOS 26…
Or you’ll have to conditionalise this code so that it only runs on iOS 26 (Claude31’s snippet shows one approach for that).

it says "Cannot find type 'TelephonyConversationManager' in scope" and similar, despite importing LiveCommunicationKit.

Could you show the code where you call and how you call.

I tested this which compiles:

import LiveCommunicationKit

override func viewDidLoad() {

          super.viewDidLoad()
          if #available(iOS 26.0, *) {
               let manager = TelephonyConversationManager.sharedInstance
          } else {
               // Fallback on earlier versions
          }
     // …
}
