Error : "Native module cannot be null."

[nuttikung]

I have tried with version 1.3.4

by the following step I did.

• yarn add react-native-callkit
• react-native link react-native-callkit
• $(SRCROOT)/../node_modules/react-native-callkit/ios/RNCallKit in header search path with recursive.
• #import "RNCallKit.h" in AppDelegate.m
• Linking Lib. with Intents.framework and CallKit.framework as optional

Do I missed any further step to complete it?

Expected Result : Application can run without any errors.
Behavior Result : Application run with error as I mentioned "Native module cannot be null."
