ReerJSON is a really fast JSON parser, and it's inspired by ZippyJSON and Ananda.

⚠️Important: When measuring the performance of Swift libraries, make sure you're building in Release Mode. When building Swift code on DEBUG compilation, it can be 10-20x slower than equivalent code on RELEASE.

Tested with ReerJSON 0.3.0, ZippyJSON 1.2.15, IkigaJSON 2.3.2

Code for Benchmarks

Add dependency in Package.swift or project Package Dependencies

.package(url: "https://github.com/reers/ReerJSON.git", from: "0.3.0"),

Depend on ReerJSON in your target.

.product(name: "ReerJSON", package: "ReerJSON" ),

Just replace JSONDecoder with ReerJSONDecoder wherever you want to use it. So instead of let decoder = JSONDecoder(), do let decoder = ReerJSONDecoder(), and everything will just work. This is because ReerJSONDecoder has the exact same API as JSONDecoder. Also, don't forget to add import ReerJSON in files where you use it.

• Add GitHub workflow for CI.
• Support CodableWithConfiguration.
• Support JSON5 decoding.
• Implement ReerJSONEncoder.
