Swift Code Checker

This tool accepts Swift code snippets and files, analyzes them for syntax correctness and basic semantic consistency. It targets individual developers, students, and code reviewers who need fast, deterministic feedback without executing code.
Core process: tokenization, grammar parsing, and lightweight AST checks; detects missing braces, mismatched types, unused imports, and simple protocol conformance mistakes. It returns a structured set of diagnostics with line/column locations and suggested fixes.
Benefits include quick validation, clear error localization, and guidance suitable for education and rapid iteration. The checker operates statically and does not compile or run code, ensuring fast turnaround and reproducible results.
Use cases include pre-submission checks, learning sessions, and lightweight code reviews where an exact compiler run is impractical. It supports multiple Swift versions at the user’s option and can be integrated into lightweight tooling or CI pipelines with minimal setup. Core features are designed to be deterministic and explainable, so developers gain insight into the root cause of a problem and a practical path to resolution.
