I am very new to Real Time Protocols and I had some questions about how WebRTC works and how I can implement it. I am trying to create a one to many livestream like facebook or periscope, where one user broadcasts and other users join and stream the video. I am using Swift from my client end.
My questions are:
I know the questions are very vague but a guidance to the right direction would be great because I am not sure where to start

WebRTC is an open-source protocol that allows for the transmission of audio, video data (in both directions), and text between browsers. It is often praised for its low latency video streaming and ability to work in peer-to-peer networks, making it a popular choice for live-streaming applications.
Netflix primarily uses DASH (Dynamic Adaptive Streaming over HTTP), but also has some other fallback encoding profiles (depending on platform). As far as I can tell, WebRTC is not used by Netflix.
WebRTC is a bit different from RTMP and HLS since it is a project rather than a protocol. Web Real-Time Communication (WebRTC) is a streaming project that was created to support web conferencing and VoIP. It was purchased by Google and further developed to make peer-to-peer streaming with real-time latency possible.
WebRTC (Web Real-Time Communication) is a technology that enables Web applications and sites to capture and optionally stream audio and/or video media, as well as to exchange arbitrary data between browsers without requiring an intermediary.
You will need to use backend servers for that.
If you plan on broadcasting to multiple users directly from your mobile app then stop...
You need to connect your mobile app to a backend media server which then can be used to broadcast the video to a larger audience.
There are several commercial and open source alternatives that enable you to do that. I'd check Red5Pro, Wowza, SwitchRTC, Jitsi, Janus and Kurento for this task.
For the client side, look at react-native-webrtc

Regarding your question (2), there's also a SDK for iOS here and a neat get-started-page here (although 2.5ys old, but I haven't found anything better so far yet)
