Hi, I'm Katsumi, a software engineer who improves the developer experience for Swift, iOS, and macOS. In my free time I've built and maintain various open-source projects of my own like:
- Swift Power Assert - Power Assert library in Swift.
- KeychainAccess - Simple Swift wrapper for Keychain that works on iOS, watchOS, tvOS, and macOS.
- SwiftFiddle - SwiftFiddle is an online playground for creating, sharing, and embedding Swift fiddles (little Swift programs that run directly in your browser).
- Swift Regex DSL Builder - Swift Regex is an online tool to learn, build and test Swift Regex Regex and Regex Builder.
- Swift AST Explorer - AST visualizer for Swift source code.
- Swift Formatter - Online playground for swift-format. You can quickly try various configurations of swift-format online.
- Apple Localization Terms Glossary - An unofficial Apple localization terms glossary that allows you to search for standard localization texts provided by the Apple platform.
- xcresulttool GitHub Action - A GitHub Action that generates a human-readable test report from the Xcode result bundle and shows it on GitHub Checks.
- WebTranslator - Unofficial Safari web extension for DeepL translate.
- IBPCollectionViewCompositionalLayout - Backport of UICollectionViewCompositionalLayout to earlier iOS 12.
- SourceKitForSafari - A browser extension for GitHub, that enables IDE features on your browser such as symbol navigator, go to definition and documentation on hover.
Working on open-source is my great joy in life and I want to be able to do that as much and as long as I possibly can. If you like what I do or if you ever made use of something I built, consider supporting me through one of the sponsor tiers here. Either a one-time donation or a monthly sponsorship is greatly appreciated. This will allow me to focus even more time on the projects I'm working on.
Thank you so much for helping me out! 👏🏻
