NSUserActivity in application(_:continue:restorationHandler:) not recognized as INStartCallIntent

Hello, experts!

I'm working on a VOIP application that handles audio calls and integrates with CallKit. The problem occurs when attempting to redial a previously made audio call from the system's call history. When I try to handle the NSUserActivity in the application(_:continue:restorationHandler:) method, it intercepts the INStartAudioCallIntent instead of the expected INStartCallIntent.

Background

• Deprecation Warnings: I'm encountering deprecation warnings when using INStartAudioCallIntent and INStartVideoCallIntent:

'INStartAudioCallIntent' was deprecated in iOS 13.0: INStartAudioCallIntent is deprecated. Please adopt INStartCallIntent instead.
'INStartVideoCallIntent' was deprecated in iOS 13.0: INStartVideoCallIntent is deprecated. Please adopt INStartCallIntent instead.

As a result, I need to migrate to INStartCallIntent instead, but the issue is that when trying to redial a call from the system’s call history, INStartAudioCallIntent is still being triggered.

• Working with Deprecated Intents: If I use INStartAudioCallIntent or INStartVideoCallIntent, everything works as expected, but I want to adopt INStartCallIntent to align with the current iOS recommendations.

Configuration:

1. CXProvider Configuration: The CXProvider is configured as follows:

let configuration = CXProviderConfiguration()
configuration.supportsVideo = true
configuration.maximumCallsPerCallGroup = 1
configuration.maximumCallGroups = 1
configuration.supportedHandleTypes = [.generic]
configuration.iconTemplateImageData = UIImage(asset: .callKitLogo)?.pngData()
let provider = CXProvider(configuration: configuration)

1. Outgoing Call Handle: When making an outgoing call, the CXHandle is created like this:

let handle = CXHandle(type: .generic, value: callId)

1. Info.plist Configuration: In the info.plist, the following key is defined:

<key>NSUserActivityTypes</key>
<array>
    <string>INStartCallIntent</string>
</array>

Problem:

When trying to redial the audio call from the system's call history, the NSUserActivity received in the application(_:continue:restorationHandler:) method is an instance of INStartAudioCallIntent instead of INStartCallIntent. This happens even though INStartCallIntent is listed in NSUserActivityTypes in the info.plist and I want to migrate to the newer intent as recommended in iOS 13+.
