What is the expected way to debug the native library?

[zahhak]

As the native library is usually spawned by a nodejs code located outside of this repository - what is the expected way to debug the calls to the spawned process?

[zahhak]

I guess it is done by waiting with lldb for the process spawn process attach --name ios-device-lib --waitfor (this could be done from xcode in debug -> attach to process by PID or Name)

That would depend on what you'd like to debug.
If you'd like to debug the C++ code you could launch the binary directly and paste a message, connected to the section you'd like to debug manually. I've added some example messages in the docs.
If you'd like to debug the Node.js you could write a sample script that reproduces some behavior and debug it in VS Code.
