Installation

Cocoapods (add to Podfile):

pod "WebRTC"

Carthage (add to Cartfile):

github "Anakros/WebRTC-iOS"

Manual: just download framework from the latest release and copy it to your project

You can only use the binary release, because the whole WebRTC repository is ~12Gb of disk space

Unstable versions

Cocoapods (will install specified unstable version or any higher version):

pod "WebRTC", ">= 14093.0.0-master"

Carthage (there is no way to auto-update to the latest unstable version at the current moment, so you should specify corresponding version tag):

github "Anakros/WebRTC-iOS" "14093.0.0-master"

Usage

Swift

import WebRTC

let device = UIDevice.string(for: UIDevice.deviceType())

print(device)
print(RTCInitializeSSL())

Objective-C

@import WebRTC;

NSString *device = [UIDevice stringForDeviceType:[UIDevice deviceType]];

NSLog(@"%@", device);
NSLog(@"%d", RTCInitializeSSL());

Bitcode

Bitcode isn't supported in the upstream for now. So you should disable it in the project build settings.
