This is a simple code for video call using WebRTC and iOS Swift.

Nowaday, Video call is a very common feature in many app. So many people(including me) start to develop that feature with WebRTC.

This link shows that how to use the WebRTC in iOS enviroment and this is the official WebRTC iOS example. However it is based on Objective C and it covers too many feature so I think there is a learning curve when I first started.

Also there are some example app using swift but I needed to make the signal server and there is a limitation to check with other platforms app like Android and web. This app is follow the official WebRTC example, so you can test this app with different platform.

This website is a WebRTC sample web. You can test the call with this app and web.

• I just use the Stun server for ice server in this example. So If you are on behide a NAT, there may be a problem.

• Exceptional case handling
• Disconnect issuce check

Additionally I developed the recording and image filter feature in video call. but I don't know it is useful for others. If I receive the request, I will add that feature in this example.

Feel free to use and fell free to contribute using PR.
