jsonparserswift

Welcome to the documentation for the JSONParserSwift library. This library provides a lightweight and efficient way to parse JSON data in your Swift projects. Whether you are working with API responses, data serialization, or any other JSON-related tasks, JSONParserSwift is here to help.

Installation

To install JSONParserSwift, you have a few options:

• Using CocoaPods:

pod 'JSONParserSwift'

• Using Swift Package Manager (SPM):

.package(url: "https://github.com/example/JSONParserSwift.git", from: "1.0.0")

• Manual installation:

You can download the library’s source code from the GitHub repository and manually add the files to your project.

Usage

Using JSONParserSwift is simple and straightforward. Here’s an example:

import JSONParserSwift

let jsonString = """
{
  "name": "John",
  "age": 30,
  "address": {
    "street": "123 Main St",
    "city": "New York"
  },
  "phoneNumbers": ["123", "456"]
}
"""

struct Person: JSONDecodable {
    var name: String
    var age: Int
    var address: Address
    var phoneNumbers: [String]

    init(json: JSON) throws {
        name = try json.value(forKey: "name")
        age = try json.value(forKey: "age")
        address = try json.value(forKey: "address")
        phoneNumbers = try json.value(forKey: "phoneNumbers")
    }
}

struct Address: JSONDecodable {
    var street: String
    var city: String

    init(json: JSON) throws {
        street = try json.value(forKey: "street")
        city = try json.value(forKey: "city")
    }
}

do {
    let json = try JSON(parse: jsonString)
    let person = try json.decode(to: Person.self)
    print(person)
} catch {
    print("Failed to parse JSON: \(error)")
}

The example above demonstrates how to parse a JSON string into a Swift object. The `Person` struct conforms to the `JSONDecodable` protocol, allowing it to be initialized from JSON data. JSONParserSwift provides various helper methods for retrieving values based on their keys. In this example, we retrieve values for `name`, `age`, `address`, and `phoneNumbers`.

Additional Functionality

Encoding JSON

In addition to parsing JSON, JSONParserSwift also supports encoding Swift objects into JSON data. Here’s an example:

struct Employee: JSONEncodable {
    var name: String
    var age: Int
    var address: Address
}

let employee = Employee(name: "Jane", age: 25, address: Address(street: "456 Elm St", city: "San Francisco"))

do {
    let json = try JSON(encode: employee)
    print(json)
} catch {
    print("Failed to encode JSON: \(error)")
}

In this example, the `Employee` struct conforms to the `JSONEncodable` protocol, allowing it to be encoded into JSON data. The resulting JSON object can be printed or used in any other JSON-related tasks.
