This is the collection of my user-defined code snippets for Xcode. Free feel to add them to your own collection.
- Clone, fork or download this collection of code snippets.
- Copy the code snippet files to:
~/Library/Developer/Xcode/UserData/CodeSnippets
To make life easier for me, I clone this repo to my CodeSnippets directory. This makes it easier for me to keep this repo up to date and simplifies sharing my code snippets across multiple machines. You can do the same, but I recommend forking this repo first so you can store your own code snippets along with the ones in this collection.
Each code snippet shortcut is prefixed with wps to avoid conflict with other shortcuts. This also groups the code snippets in the Code Completion window.

Learn more about using and creating your own Code Snippets from this article, Be More Productive in Xcode Using Code Snippets.
lscs.py is a python script that lists the code snippets for the current user. The listing shows the title, shortcut, and summary for each code snippet file.
Example: python lscs.py
lscs.py is also used to create the list of code snippets shown above. You can do the same by using the -f markdown (or --format=markdown) command line parameter.
Example: python lscs.py --f markdown
There is absolutely no support offered for this collection of code snippets. You're on your own! However, free feel to send me a message or even a pull request if you have an interesting and useful code snippet to share.
