SwiftLint is a static analysis tool and code formatter designed to enforce consistent coding styles and identify semantic issues within Swift source code. It functions as a command-line utility that evaluates code against established conventions to ensure uniform structure and architectural standards across a project.
The tool distinguishes itself through a custom linting engine that leverages compiler-integrated syntax analysis to perform deep inspections of code structure. Beyond simple pattern matching, it supports automated source code transformation to correct formatting violations and resolve style errors directly within the source files.
The project provides extensive support for custom validation logic, allowing developers to define bespoke rules using regular expressions or native code to meet specific project requirements. It also manages complex environments through hierarchical configuration merging, which enables the application of consistent rules across large, modular codebases by resolving inheritance and local overrides.
