Stream based JSON parsing on Swift

Question

How to parse JSON being downloaded as a stream on Swift? The stream gives incomplete JSON data each time. This is because I have to download MBs of data, the main component of which is a long array of objects, and I do not want the user to wait till I get the complete data. Is it possible to keep parsing the JSON data sequentially while streaming? Basically, something like what Jackson allows on Android, or a YAJLiOS Parser implementation for Swift

Wow, no action on this in over a year and a half. – Methylamine

JSON parsing is not hard at all. Why not write your own parser? – Thor

Maybe is better approach if you send the json from the server in parts. I mean, X number of elements each time – Farant

Basically, what you require is a SAX parser. NSJSONSerialization is a DOM parser. One such implementation for sax parsing is here

where the data is parsed as and when the data is received. For more info check this answer iPad - Parsing an extremely huge json - File (between 50 and 100 mb)

Yeah, this is again an Obj-C based approach. I was looking for something Swift based actually. – Suppose
