Where is the output?

I have followed the guide and it builds successfully but cannot find the output Swift file?

CodegenKit does not output new source code files.
Instead, it edits the user’s provided source code directly.
The input source code should include the @codegen directive.
CodegenKit rewrites these parts directly and uses them as the output.
Therefore, users do not need to change their build configuration when introducing code generation.
