voice-quickstart-ios: iOS 13 App built on Xcode 11 Crashes when receiving call if the app is on background or killed

Description

I have a react-native application that use a home built component to handle Twilio communication. We have upgraded to latest 5.x twilio iOS SDK and latest Android SDK. On Android it works great. On iOS the calls work perfect when the app is in foreground but it fails when the app is killed and the phone locked. I followed all the issues and the migration guides to no avail. I’m sure there’s something wrong in the code as I’m experiencing what is described in issue #251 but I’m not sure what’s wrong. When the phone is killed pushRegistry:didReceiveIncomingPushWithPayload:forType:withCompletionHandler is never called and then I get an error saying Killing VoIP app <private> because it failed to post an incoming call in time.

Steps to Reproduce

Launch application in iphone with iOS 13.x and log in. Make sure Twilio is registered
Kill the app and lock the phone
Call the locked phone.
Application starts in XCode Debug, but is killed with Killing VoIP app <private> because it failed to post an incoming call in time. Error.

Expected Behavior

That I receive a call

Actual Behavior

Nothing happens.

Reproduces How Often

Do this first, Important! Screenshot 2021-03-26 at 10 12 06 AM

Add below code is inside : func pushRegistry(_ registry: PKPushRegistry, didReceiveIncomingPushWith payload: PKPushPayload, for type: PKPushType, completion: @escaping () -> Void)

Use completion() in main thread.

PKRegistryDelegate needs to be registered during the launch or quickly as possible else you never get the Push.
Call provider.reportNewIncomingCall inside didReceiveIncomingPushWith
Use completion() in main thread.

These steps solved my problem.

@bchen-twilio thanks for your quick reply.

I have already implemented it on the AppDelegate. Code is in this comment https://github.com/twilio/voice-quickstart-ios/issues/308#issuecomment-614210246
Following are the call ID which were repored with delay.

Sure, I’ll do that and I will also use the same library in a new application without any other library to see if it works. Thanks @bchen-twilio
