#Xcode Swift Code Snippets
I want to present you some convenient code snippets I gathered recently for Swift. As Swift becomes more and more popular, it gains CocoaPods support and probably more and more people will be using it.
##Inspiration I was inspired by Matt Thompson's Xcode-Snippets article and GitHub repo but I haven't found anything similar for Swift.
I also used that thing in swift and SwiftSingleton as a sample implementations.
##How to import all code snippets to Xcode
All Xcode code snippets exist as a .plist
files in ~/Library/Developer/Xcode/UserData/CodeSnippets/
You can simply copy all code snippets from plist
directory in this repo into this folder, restart Xcode and you should have all of them ready to use.
Note: Create the folder if the folder doesn't exist already. It is created by Xcode when user adds their first cusom snippet.
##Usage
I named all of snippets using scheme Swift ...
and set all Completion Shortcuts to swift-...
so each time you type swift
in code editor you should see all snippets you can use in that place.
##How to create your own snippets
To add code snippet to Xcode show Utilities right panel and press {}
button (Show the Code Snippet library) in lower panel.
Then select a code you would like to treat as a snippet, press and hold a left mouse button for a while and drag whole selection to the right panel (if you drag to early you'll probably only deselect text; you can also try dragging from a whitespace instead of the letter).
###Placeholder tokens
If you want to add this nice placeholder in rounded blue rect simply put it between <#
and #>
and it will be transformed in both editor and final snippet.
##Snippets Currently existing snippets (I hope they will be updated on a regular basis with your help :) ):

##More snippets?
This is a good start but I encourage you to create your own snippets or correct existing ones and create Pull Requests. Please provide plain snippet as .swift
source code as well as its .plist
counterpart so it can be easily imported.
You can use plist/generate_list.py
script to generate snippets list by running: python generate_list.py
.
