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've been trying to understand what kind of UX is available if my app is using the default-dialer capability. I have found https://developer.apple.com/documentation/livecommunicationkit/preparing-your-app-to-be-the-default-dialer-app and I am in the EU. On android I built the UX I want and it's quite neat, so now I'm trying to work. out what I can get on iOS. Because the product is kind of worthless with just android. I have built a simple dialer ux with a numberpad, contact lookup etc. Then when the user presses the Call button does it have to pop up the system prompt "Call number"? Does it have to swap over to the system ui for the actual call? So there's no way to show information about the call, during the call? Or am I using the frameworks incorrectly? I am very new to iOS development. TrueCaller and others show validation, but as I understand it they pre-fetch all the data, I can't do that.
