[swift-corelibs-dev] swift-corelibs-dev Digest, Vol 1, Issue 18

Fri Dec 4 15:35:42 CST 2015

While I totally agree that that is a great long term goal, getting Swift running JSON parsing on the server as fast as humanly possible is a priority for many people. Would it be acceptable to vendor a minimal JSON tokenizer like jsmn to handle the brunt of the implementation, until such time as we can write one ourselves?

Tom, I’d love to collaborate with you on NSJSONSerialization and take some ownership of enhancing this crucial slice of Foundation. It’ll touch on many aspects of Foundation’s data types and as such will make a great platform for unearthing bugs elsewhere and serving as an integration test.

Thomas

I already have written a wrapper that uses yajl to take a CFDictionaryRef or CFArrayRef and encodes them into CFDataRef or CFStringRef JSON values.. Is it acceptable to use yajl and introduce a dependency, or is it a goal of the foundation project to supply its own implementation of a JSON parser?

There are certainly some areas where we require the functionality provided by the Apple ICU but we have just omitted those from the build on Linux for the time being (look for __HAS_APPLE_ICU__ in CF). Eventually we’ll have to figure out a unified story for this.
