Paste JSON as Code • quicktype
Paste JSON as Code • quicktype is an Xcode extension that infers types from sample JSON data and generates strongly typed models and serializers for working with that data. It supports Swift, Objective-C, C++, Java and other languages, allowing developers to quickly convert JSON structures into type-safe code. The extension integrates directly into Xcode and is also available as a standalone web tool at app.quicktype.io, making it useful for API development, data parsing, and code generation workflows.
AI Recommendation
1 suggestionThe search results show quicktype version 8.2.22 was released in January 2018 with no subsequent updates documented. The app has not been actively maintained for over six years, and there is no evidence in the available search results of a native Apple Silicon build. However, the online version at app.quicktype.io remains accessible and functional, providing the same core type-inference and code-generation capability through a modern web interface that runs natively in any browser on Apple Silicon Macs. If you rely on the Xcode extension, contact the developer (David Siegel) to ask whether a native Apple Silicon build or update is planned before macOS 28 removes Rosetta 2 support in September 2028. In the meantime, the web tool at app.quicktype.io is the most reliable way to continue using quicktype's functionality without depending on the aging Xcode extension.
