Overview

The sandbox provides support for the directory that CocoaPods uses for an installation. In this directory the Pods projects, the support files and the sources of the Pods are stored.

CocoaPods assumes to have control of the sandbox.

Once completed the sandbox will have the following file structure:

   Pods
   |
   +-- Headers
   |   +-- Private
   |   |   +-- [Pod Name]
   |   +-- Public
   |       +-- [Pod Name]
   |
   +-- Local Podspecs
   |   +-- External Sources
   |   +-- Normal Sources
   |
   +-- Target Support Files
   |   +-- [Target Name]
   |       +-- Pods-acknowledgements.markdown
   |       +-- Pods-acknowledgements.plist
   |       +-- Pods-dummy.m
   |       +-- Pods-prefix.pch
   |       +-- Pods.xcconfig
   |
   +-- [Pod Name]
   |
   +-- Manifest.lock
   |
   +-- Pods.xcodeproj
(if installation option 'generate_multiple_pod_projects' is enabled)
   |
   +-- PodTarget1.xcodeproj
   |
  ...
   |
   +-- PodTargetN.xcodeproj
