How to automate xcode clean process using fastlane Fastfile lane

Question

I am looking for a way to automate xcode clean process using fastlate.

What I am looking to achieve:

1. Clear Derived Data Folder
2. Clean build folder
3. Clean
4. Build

So far I automated the derived data folder

lane :clean do
  clear_derived_data
end

Answer 1

You have achieve 1,2 and 3, but for 4, you need to use Gym It's easy to use, follow his guide https://docs.fastlane.tools/actions/gym/

lane :cleanAndBuild do
  clear_derived_data
  gym( my_params )
end
