Script to remove Xcode storyboard for iOS/Swift projects

When you create a new project with Xcode, then this script

1. removes the file Main.storyboard
2. removes the reference to it in the .pbxproj file (i.e. it will disappear from the Project Navigator)
3. edits the Info.plist and deletes the UIMainStoryboardFile entry there
4. edits the AppDelegate.swift file so that the ViewController is set as root view controller via code

Installation:

$ ./install.sh $YOUR_SCRIPT_DIRECTORY # should be in your $PATH

Usage:

$ cd $PROJECT_DIRECTORY
$ remove_storyboard
