CallKit Video button disabled

Question

I have integrated CallKit successfully and I'm trying to handle the video button. In some devices, I get the enabled video button and can request to open a video connection. But for some devices, I get a disabled video icon. What could be the reason for that?

private lazy var provider: CXProvider = {
 let configuration = CXProviderConfiguration()
 configuration.supportsVideo = true
 configuration.maximumCallGroups = 2
 configuration.maximumCallsPerCallGroup = 4
 configuration.includesCallsInRecents = false
 configuration.supportedHandleTypes = [.generic]
 return CXProvider(configuration: configuration)
}()
func reportIncomingCall() {
 let uuid = UUID()
 let update = CXCallUpdate()
 update.supportsGrouping = true
 update.supportsHolding = true
 update.remoteHandle = CXHandle(type: .generic, value: "Name")
 update.hasVideo = true // or false
 provider.reportNewIncomingCall(with: uuid, update: update) { [weak self] error in
 // handle 
 }
}

enter image description here

Note: Whatsapp has the enabled video button in the same device.

• iOS Developer: Did you try removing 'update.hasVideo' assignment from the reportIncomingCall() function altogether since you're always setting it to true.
• ajw: Hey @iOSDeveloper, Yes I did and there's no difference from that.
• Chetan A: Check the video permission for you app in the settings.
• ajw: Hey @ChetanA, which permission exactly are you referring to?
• Chetan A: As you have highlighted the example of Whatsapp in your question, I would suggest you to check the permission of both the Watsapp and your application on the device. If you disable the Microphone and Camera then you will not be able to make video calls and button would be disabled.
