SyntaxKit is a lightweight Swift package that makes generating Swift code more intuitive and declarative.
Powered by SwiftSyntax and Swift’s result builders, SyntaxKit lets developers build complex Swift code structures with clear, expressive syntax.
Instead of manually stitching together strings or syntax trees, you can use result builders to define code elements like functions, declarations, and statements in a readable, Swift-native way.
The builders make it easy to create tools like code generators, linters, or source transformations, all while working entirely in Swift.
Key Features
- Declarative Swift code generation
- Composable & type-safe
- Open source & lightweight
Pros & Cons
| Pros | Cons |
| Feels natural for Swift developers thanks to result builders. | Requires familiarity with SwiftSyntax and result builders, which can be non-trivial for beginners. |
| Eliminates manual string concatenation or error-prone syntax tree manipulation. | |
| Works for a range of use cases like code generation, linters, static analysis tools, or custom Swift plugins. |
Pricing & Plans
SyntaxKit is free to use. It’s released under the permissive MIT License, which means that you can integrate, modify, and distribute it in both personal and commercial projects without any fees or restrictions.
Conclusion
SyntaxKit is a simple, Swift-native way to generate Swift code safely and declaratively. By combining SwiftSyntax with result builders, it makes complex code generation clear and maintainable.
No more worries about manual string stitching or error-prone syntax trees. It’s free, open source, and easy to integrate, making it a great tool for anyone building code generators, linters, or static analysis tools in Swift.
