Xcode 4 introduced code snippets; small, re-usable chunks of code that could be inserted using Xcode's native auto-completion system.
The problem is, Xcode does little to nothing to help you manage these snippets. There isn't an easy way of sharing them or managing them.
xcodesnippets aims to make snippets a little bit more manageable, and sharable through the concept of snippet bundles.
My hope is that one day that this utility becomes obsolete and Xcode itself has better support for managing snippets, including organisation into folders and native installation/activation/deactivation of snippet bundles. To that end, I have filed a bug (rdar://9587558) which I encourage you to dupe if you feel this would be beneficial.
xcodesnippets is written in Ruby and distributed as a Ruby gem. Most Macs with development tools installed come with a usable version of Ruby and RubyGems although to date, this gem has only been tested against Ruby 1.9.2. If you have a problem, please file a bug.
If you aren't familiar with RubyGems, fire up a Terminal and run the following command:
$ sudo gem install xcodesnippets
If you are using a tool like RVM, the
sudo will probably be unnecessary.
Migrating your existing snippets
If you already have some snippets in
~/Library/Developer/Xcode/UserData/CodeSnippets/ you will want to bring these under
xcodesnippets control before you do anything else.
xcodesnippets will do this for you; not only that, but it will rename each snippet file to use a more meaningful title (the one you gave it within Xcode).
To migrate your exiting snippets, run:
$ xcodesnippets migrate
A list of your existing snippets will be displayed and with your confirmation, they will be copied into the default
xcodesnippet bundle, removed from the Xcode snippets directory, then re-linked back to the
xcodesnippet versions (see "How xcodesnippets works" for more).
Installing a code snippet
Code snippets are distributed as property list files with a
.codesnippet extension. If you have created any custom code snippets in Xcode 4, you will find them in your home directory, under
~/Library/Developer/Xcode/UserData/CodeSnippets/. The files are named using GUIDs. Any
codesnippet file created from within Xcode 4, or manually if you are comfortable editing the files yourself (they are just plists) are installable using
To install a snippet, run the following from the terminal:
$ xcodesnippets install [path-to-snippet-file]
To install a bundle, run the following:
$ xcodesnippets install-bundle [path-to-snippet-bundle]

How xcodesnippets works
xcodesnippets stores all of it's snippets inside snippet bundles. Snippet bundles are simply a directory/package with a
.snippetbundle extension. When creating and sharing snippets, you are encouraged to give them a suitable name that indicates what the snippet does, rather than using the GUID naming scheme that Xcode uses.
xcodesnippets installs all of it's snippets into
~/Library/Developer/Xcode/UserData/ManagedCodeSnippets. Standalone snippets are stored in a default snippet bundle. Snippets are then symlinked from their installed location to the Xcode code snippets directory with an appropriate GUID, ensuring that they appear in Xcode (you may need to close your current project or workspace before installed snippets appear).

- Activating snippets from outside the managed directory - great for using your own snippets from their local source repos.
- Generating snippet bundles from a folder of snippets ready for distribution
- Commands for listing installed bundles and their contents
- Commands for activating and de-activating individual bundles/snippets
