Draft:SwiftLint 2

SwiftLint, is a static code analysis tool for the Swift programming language, that aims to enforce good Swift style and conventions. The creator and lead developer is JP Simard.

SwiftLint is free software under the MIT license.

Features
SwiftLint's checks are implemented as rules, which are either on by default, or opt-in.

Over 230 rules are built in to SwiftLint, and users can define additional custom rules using regular expressions.

For example, the rule warns, or errors if identifiers (e.g. variable and function names) are too short or too long, and allows the warning and error thresholds for length, as well as identifiers that should be ignored by the rule (such as   and  ), to be configured.

SwiftLint is also capable of auto-correcting certain kinds of violations.

SwiftLint has an analyzer mode, which can check for unused code and imports using the abstract syntax tree, but runs more slowly than the usual lint mode.
