Overview

The Installer is responsible of taking a Podfile and transform it in the Pods libraries. It also integrates the user project so the Pods libraries can be used out of the box.

The Installer is capable of doing incremental updates to an existing Pod installation.

The Installer gets the information that it needs mainly from 3 files:

- Podfile: The specification written by the user that contains
  information about targets and Pods.
- Podfile.lock: Contains information about the pods that were previously
  installed and in concert with the Podfile provides information about
  which specific version of a Pod should be installed. This file is
  ignored in update mode.
- Manifest.lock: A file contained in the Pods folder that keeps track of
  the pods installed in the local machine. This files is used once the
  exact versions of the Pods has been computed to detect if that version
  is already installed. This file is not intended to be kept under source
  control and is a copy of the Podfile.lock.

The Installer is designed to work in environments where the Podfile folder is under source control and environments where it is not. The rest of the files, like the user project and the workspace are assumed to be under source control.

end

#install! ⇒ void

This method returns an undefined value.

Installs the Pods.

The installation process is mostly linear with a few minor complications to keep in mind:

  • The stored podspecs need to be cleaned before the resolution step otherwise the sandbox might return an old podspec and not download the new one from an external source.

  • The resolver might trigger the download of Pods from external sources necessary to retrieve their podspec (unless it is instructed not to do it).
