I want to present some convenient code snippets I gathered for Swift.
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.
All Xcode code snippets exist as a .plist files in ~/Library/Developer/Xcode/UserData/CodeSnippets/
You can simply copy all code snippets (.codesnippet) into this folder, restart Xcode and you should have all of them ready to use.
Note: Create the folder if it doesn't exist already. It is created by Xcode when user adds his first custom snippet.
I named all 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.
To add code snippet to Xcode expand 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 too early you'll probably only deselect text; you can also try dragging from a whitespace instead of the letter).
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.
Currently existing snippets (I hope they will be updated on a regular basis with your help :) ):

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 snippets as .plist files so they can be easily imported.
You can use plist/generate_list.py script to generate snippets list by running: python generate_list.py.
