iOS Cocoa Touch Universal Framework Script

What

For an framework to be compatible with various devices it has to be compiled for them specifically, This script does those tasks in single shot.

How

Install Script

1. Select Target
2. [ ⌘ + ⌥ + i] Command + alt + i.  
3. Archive > Post-actions > + > New run script action
4. Provide build settings from : SELECT YOUR TARGET
5. copy and paste this script in the script area.

Build Settings

1. Select Target > Build Settings > Skip Install
2. Ensure that it is set to NO

Why

Due to some bug in Xcode, this is not done automatically.
