Caller ID doesn't work in my phone

[SamaritanMachine]

I tried many solution for CallKit extension to show caller id.

Steps:

1 - Adding call directory extension to my project. 2 - Set the developer.apple.com things. 3 - Implement the code. (For testing, both phone numbers array which is stored in userDefaults and static number.) 4 - Allow my app in device settings

But it didn't work. Do I have to add any code in appdelegate or somewhere else? Can you help me?
