WebRTC binary for SwiftPM (unfinished)

This project holds binaries of WebRTC framework (iOS & macOS) as releases.

Since release M122-1 we publish WebRTC framework as XCFramework compiled for:

• iOS
• iOS Simulator (Intel)
• iOS Simulaotr (AppleSilicon)
• macOS (Intel)
• macOS (AppleSilicon)

Currently usage of macOS universal binary (FAT) was not yet tested.

Building XCFramework

Download webrtc

git clone https://chromium.googlesource.com/chromium/tools/depot_tools.git
export PATH=$PATH:/path/to/depot_tools

fetch --nohooks webrtc_ios

git branch -r
git checkout branch-heads/BRANCH

gclient sync
