WebRTC' does not contain bitcode You must rebuild it with bitcode enabled (Xcode setting ENABLE_BITCODE)

Solution 1:

you need to remove bitcode in your ios project setting in xcode target->build settings-> enable bitcode or use a custom webrtc build that enable it at compile time (huge build). I made one here

edit: a build with bitcode and swiftmodule support This Repo also have sh script that explain the procedure.
