## What it is
A curated collection of Swift tips and tricks originally shared by John Sundell on Twitter, organized as a numbered list with links to the original tweets. It covers language features, testing patterns, and idiomatic Swift techniques, and is no longer updated in favor of the Swift by Sundell website.

## Use cases

- find references to Swift tips from Twitter

## When to choose
- you want a free, curated list of practical Swift tips
- you are learning Swift and want bite-sized examples
- you want links to community discussion for each tip

## When to avoid
- you need up-to-date tips for the latest Swift versions
- you need structured tutorials or a full course rather than short snippets
- you need runnable library code rather than educational content
