Introduction
MeToVaJSONCodable is a Swift library that provides a set of protocols and extensions to simplify JSON decoding and encoding using the Codable protocol.
Requirements
- Swift 4.2 or later
Installation
To integrate MeToVaJSONCodable into your Xcode project, you can use CocoaPods or Swift Package Manager.
Using CocoaPods
- Add the following line to your Podfile:
- Run `pod install` in your project directory.
- Import MeToVaJSONCodable in your Swift files:
“`ruby
pod ‘MeToVaJSONCodable’
“`
“`swift
import MeToVaJSONCodable
“`
Using Swift Package Manager
- In Xcode, go to `File > Swift Packages > Add Package Dependency`
- Enter the URL of the MeToVaJSONCodable GitHub repository:
- Follow the steps onscreen to add the package to your project.
- Import MeToVaJSONCodable in your Swift files:
“`
https://github.com/example/MeToVaJSONCodable.git
“`
“`swift
import MeToVaJSONCodable
“`
Usage
To decode or encode JSON using MeToVaJSONCodable, you need to conform to the `MeToVaJSONDecodable` or `MeToVaJSONEncodable` protocol respectively. These protocols extend the Codable protocol and provide additional functionality.
Decoding JSON
- Define your Swift struct or class conforming to `MeToVaJSONDecodable`:
- Decode the JSON using the `MeToVaJSONDecoder.decode(data:)` method:
“`swift
struct Person: MeToVaJSONDecodable {
var name: String
var age: Int
var address: String
enum CodingKeys: String, CodingKey {
case name
case age
case address = “fullAddress”
}
}
“`
“`swift
if let jsonData = jsonString.data(using: .utf8) {
do {
let person = try MeToVaJSONDecoder().decode(Person.self, from: jsonData)
// Use the decoded person object
} catch {
// Handle decoding error
}
}
“`
Encoding JSON
- Define your Swift struct or class conforming to `MeToVaJSONEncodable`:
- Encode the object to JSON using the `MeToVaJSONEncoder.encode(object:)` method:
“`swift
struct Person: MeToVaJSONEncodable {
var name: String
var age: Int
var address: String
enum CodingKeys: String, CodingKey {
case name
case age
case address = “fullAddress”
}
}
“`
“`swift
let person = Person(name: “John Doe”, age: 30, address: “123 Main St”)
do {
let jsonData = try MeToVaJSONEncoder().encode(person)
if let jsonString = String(data: jsonData, encoding: .utf8) {
// Use the encoded JSON string
}
} catch {
// Handle encoding error
}
“`
Conclusion
MeToVaJSONCodable provides a convenient way to decode and encode JSON using the Codable protocol. With its easy-to-use API, you can quickly integrate JSON functionality into your Swift projects.
