[iOS SDK] Looking for guidance to start contributing

[Saurabh Mishra]

 Hi everyone,
I'm an iOS developer and want to understand WebRTC internals and contribute to the iOS SDK. I'd appreciate guidance or mentorship on:
1. Which "good first bugs" are suitable for iOS newcomers
2. Are there any areas of the iOS SDK that need attention and I can contribute
3. Any recommended reading order for understanding the codebas
I'm happy to start with documentation, tests, or small bug fixes to learn the contribution workflow.
Thanks in advance!
