The Discussion
Extensions
What are they
Turns out..."Extensions" is not a single concept. Multiple flavors known as extension points.
App Extension lets you extend custom functionality and content beyond your app and make it available to users while they’re using other apps.
App Extensions are a separate binary that runs independent of your app.
Extensions Points
Today - interact with the “Today” view of notification center
Share - Post to sharing website (twitter) or share content with others
Action - manipulate or view content within the context of another app
Photo Editing - edit a photo with Photos app
Finder (OS X only) won’t discuss
Document Provider - manager files
Custom Keyboard - replace custom keyboard
Apple is really stressing “Trust” as a key when creating a custom keyboard. Your users are giving you access to everything they type including passwords and other sensitive data.
App extension must exactly match one of the types of extensions. You can’t create a generic extension that matches more than one extension points.
What can’t they do
Access a sharedApplication object
Use any API marked in header files with the NS_EXTENSION_UNAVAILABLE macro
Access camera or mic
Perform background tasks
Receive data via AirDrop
Distribution
App Extensions must be delivered via a Containing App on iOS.
Common Needs
Sharing data with containing app requires special considerations. Need to use a share container. Watch out for data corruption/
Deploying to older version of iOS
Need to take advantage of conditional linking
Use dlopen command if systemVersion return iOS 8.0 or later
Open-Source project of the week
https://github.com/ioscreator/ioscreator
Contains tons, and I do mean tons, of code samples for doing just about everything under the sun on iOS.
Great for someone looking to try something new or for those just getting started with iOS development.

Synalyze It!
Synalyze It! allows you to create a grammar for your binary files interactively (or you can download shared grammars for common file formats). Unlike in regular hex editors or viewers the files are interpreted automatically for you. Additionally Synalyze It! is a full-featured Hex Editor for Mac OS X allowing you to edit files of unlimited size and interpret the bytes with dozens of text encodings.
