App Extensions for iOS development.

App Extensions for iOS development. App extensions give users access to your app’s functionality and content throughout iOS 8 and OS X Yosemite.

Starting in iOS 8.0 and OS X v10.10, an app extension lets you extend custom functionality and content beyond your app and make it available to users while they’re using other apps or the system. You create an app extension to enable a specific task; after users get your extension, they can use it to perform that task in a variety of contexts

Source: Apple App Extensions Document

iOS and OS X define several types of app extensions, each of which is tied to an area of the system, such as:

  • Share
  • Today
  • Photo Editing
  • CustomKeyboard
  • File Provider
  • Document Provider
  • Actions
  • Finder Sync
