{N} CLI supports only static libraries built for all required architectures (universal* libraries).
hello-plugin contains an universal library
bye-plugin contains a non-universal library
universal - a library is called universal when it is build for all required architectures:
- iOS Devices - armv7 and arm64,
- (OS X) iOS Simulators - i386 and х86_64.

lipo -i <path_to_staticLib.a>
