Having a problem with CallKit integration. I am creating a configuration like this:
let providerConfiguration = CXProviderConfiguration(localizedName: "XXX")
providerConfiguration.supportsVideo = false
providerConfiguration.maximumCallsPerCallGroup = 1
providerConfiguration.supportedHandleTypes = [.phoneNumber]
if let callKitIcon = UIImage(named: "IconMask")
{
providerConfiguration.iconTemplateImageData = callKitIcon.pngData()
}
providerConfiguration.ringtoneSound = "Ringtone.caf"
And then creating the provider like so:
self.provider = CXProvider(configuration: providerConfiguration)
self.provider.setDelegate(self, queue: nil)
Problem is that all of this seems to be ignored. Custom Ringtone does not sound, IconMask does not show up on the iOS UI (its just a blank). IconMask is correct and the 3 images are 40, 80 and 120 pixels with alpha channel. Ringtone.caf is a valid sound file copied in the bundle.
Nothing in this CXProviderConfiguration seems to have any impact at all. Very frustrating! I get called back on the delegate function:
func providerDidBegin(_ provider: CXProvider)
And there I can inspect provider.configuration and it all looks correct. What am I doing wrong?
The inbound call actually works and I am integrating with TwilioVoice and VOIP push. So just the UI is not picking up anything in the configuration.
