I have Build webRTC and My App Accessing WebRTC API through another static library viz. LibB When I link LibB with my application and build it , it fails with below log: **** I have build WebRTC against AMD64/ARMv7** Undefined symbols for architecture arm64:

You have to generate the framework for arm64 and arm at the same time

Use these commands:

gn gen out/Debug-device --args='target_os="ios" target_cpu="x64" is_component_build=false additional_target_cpus=["arm", "arm64"] enable_dsyms=true ios_enable_code_signing = false'

ninja -C out/Debug-device rtc_sdk_framework_objc
