TidyJSON

TidyJSON is a neat and tidy JSON package run on all Swift platforms (Linux, iOS, OS X, tvOS, watchOS)

This branch using Swift 3.0

Goals

• [x] simple, neat and tidy json lib
• [x] safe static typed without Any or AnyObject
• [x] performance
• [x] pure Swift, only dependent to builtin types
• [x] compatible with all Swift platforms (Linux, iOS, OS X, tvOS, watchOS)
• [x] concise usage
• [x] boxing dict and array type for mutating data
• [x] modify json via subscript operator
• [x] fully tested
• [x] better parse error report
• [x] Swift Package Manager, Carthage support

Usage

Literal Convertible

Literal value can be type safe converted to TidyJSON.JSON like this:

let jsonFalse : JSON = false
let jsonTrue : JSON = true
let jsonNull : JSON = nil
let jsonNumber : JSON = 1.2e-2
let jsonString : JSON = "hello swift"
let jsonArray : JSON = [12, "string", false, nil, true, ["nested array", 12, 1.2], ["nested dict": nil]]
let json : JSON = ["key":false, "key2":true, "key3":[1, "hello", 3, "world", ["key4":nil, "key5":12.03, "key6":12E-2, "key7": -12e-2]]]

Access value

Get and Set value via Subscripts:

var json : JSON = []
// []

let child :JSON = "string"
json.append(child)
// ["string"]

json[0] = "STRING"
// ["STRING"]

json.append(JSON([]))
// ["STRING", []]

json[1].append(JSON("hello"))
// ["STRING", ["hello"]]

json[1][0] = "world" 
// ["STRING", ["world"]]

json[1].removeAtIndex(0)  
// ["STRING", []]

json.removeAtIndex(1)
// ["STRING"]

var json1 : JSON = [:]
// {}
json1["hello"] = false 
// {"hello":false}

json1["world"] = true
// {"hello":false, "world":true}

// remove a key
json1["hello"] = nil
// {"world":true}

json1["world"] = [1,2,3]
// {"world":[1,2,3]}

Parse from String

let json1 = try! JSON.parse("{\"key\" : false }")
if let b = json1["key"].bool {
    print(b)
}
/*
false
*/

let json2 = try! JSON.parse("{\"key\" : [\" \\u0041334 \\n \\t \\\" \"]}")

if let x = json2["key"][0].string {
    print(x)
}
/*
 A334 
         " 
*/

Loop

let jsonArray : JSON = [12, "string", false, nil, true]
// for Array, key is string of current index
for (k, v) in jsonArray {
    print("key: \(k), value: \(v)")
}
/* 
key: 0, value: Number(12.0)
key: 1, value: String("string")
key: 2, value: Boolean(false)
key: 3, value: Null
key: 4, value: Boolean(true)
*/

let json : JSON = ["key1":false, "key2":true, "key3": 123, "key4": "hello"]

for (k, v) in json {
    print("key: \(k), value: \(v)")
}
/*
key: key, value: Boolean(false)
key: key2, value: Boolean(true)
key: key4, value: String("hello")
key: key1, value: Boolean(false)
key: key3, value: Number(123.0)
*/

Dump to String

let json2 = try! JSON.parse("{\"key\" : \" \\u0041334 \\n \\t \\\" \"}")
print(json2.dump())
// {"key":" A334 \n \t \" "}

Test

On Linux platform you need install XCTest

After install XCTest, run swift build then swift test

Integration

Carthage

To integrate TidyJSON into your Xcode project using Carthage, specify it in your Cartfile:

github "benloong/TidyJSON"

Swift Package Manager

Currently support Swift Package Manager to install TidyJSON by adding the proper description to your Package.swift file:

import PackageDescription

let package = Package(
    name: "YOUR_PROJECT_NAME",
    targets: [],
    dependencies: [
        .Package(url: "https://github.com/benloong/TidyJSON.git", majorVersion: 1)
    ]
)
