Simple file caching & manipulation in iOS
This document is heavily influenced by Apple docs (Jump: Browse to the sample code on Github) For security purposes, an iOS app’s interactions with the file system are limited to the directories inside the app’s sandbox directory. During installation of a new app, the installer creates a number of container directories for the app inside the sandbox directory. Each container directory has a specific role. The bundle container directory holds the app’s bundle, whereas the data container directory holds data for both the app and the user.
