JSONSwift

JSON parser in pure swift

A JSON parser written from the ground up in pure Swift. It is a functional recursive descent parser.

Installing

Copy "JsonParse.swift" file into your project. Or just import the framework. That's it. :)

How to use:

Parse JSON Object

// Data

{
    "MONDAY": [
        {
            "TITLE":   "TEST DRIVEN DEVELOPMENT",
            "SPEAKER": "JASON SHAPIRO",
            "TIME": "9:00 AM"
        },
        {
            "TITLE": "JAVA TOOLS",
            "SPEAKER": "JIM WHITE",
            "TIME": "9:00 AM"
        }
    ],
    "TUESDAY": [
        {
            "TITLE": "MONGODB",
            "SPEAKER": "DAVINMICKELSON",
            "TIME": "1: 00PM"
        },
        {
            "TITLE": "DEBUGGINGWITHXCODE",
            "SPEAKER": "JASONSHAPIRO",
            "TIME": "1: 00PM",
        }
    ]
}

Just call the method jsonParse with the jsonData string

if let data : [String: AnyObject] =  jsonParse(fileContent!),
    let monday = data["MONDAY"] as? [AnyObject]  {
        for course in monday {
            if let title = course["TITLE"] as? String {
                println(title)
            }
        }
}

Parse JSON Array

// Data
[
    {
        "Name" : "Jhon"
        "ID" : 176
    },		
    {
        "Name" : "Dexter"
        "ID" : 193
    },
    {
        "Name" : "Wick"
        "ID" : 122
    }
]

Just call the method jsonParse with the jsonData string

if let data : Array =  jsonParse(input){
    for object in data {
        if let elem = object as? [String: AnyObject] {
            println(elem["Name"]!)
            println(elem["ID"]!)
        }
    }
}

Parse twitter JSON..

Sample twitter data from twitter search API

{
    statuses: [
        {
        ...
        ...
        "text": "The tweet is here"
        ...
        ...
    },
        {
        ...
        ...
        "text": "The second tweet is here"
        ...
        ...
    }	
    ]
}

Access tweets from Json returned by twitter API

if let data : [String: AnyObject] = jsonParse(input), 
    let statuses = data["statuses"] as? [AnyObject]{
    for elem in statuses {

    if let tweet = elem as? [String: AnyObject],
        let text : String = tweet["text"] as? String {
            println(text)
            }
        }
    }
