                Generating Lenses helpers using Sourcery
              
          
        
      
        
  
      
    What are Lenses? Great explanation by @mbrandonw
Files:

input.swift - sample structs for which we want helpers to be generated
lens.stencil - sourcery template to generate lenses helpers
output.swift - sample lenses helpers generated
zLens.swift - simple implementation of lenses, so you can play with it

Hints:

Usually you want to generate helpers only for certain structs in your project. To limit scope of sourcery changes, keep your relevant structs under one directory and just point sourcery to that directory instead of whole project.
