## What is EVReflection?
EVReflection is a lightweight library that simplifies working with JSON and Swift classes. It helps you convert JSON strings to instances of Swift classes effortlessly, and vice versa.
## Features
### JSON to Swift Class Conversion
EVReflection offers a simple and convenient way to convert JSON strings into Swift class instances. It automatically maps JSON keys to properties of the Swift class, saving you from writing boilerplate code and reducing your development time.
### Swift Class to JSON Conversion
With EVReflection, you can effortlessly convert your Swift class objects into JSON strings. This feature comes in handy when you need to send data over a network or store it persistently.
### Protocols for Custom Mapping
EVReflection provides protocols that enable you to customize the mapping between JSON keys and Swift class properties. This gives you full control over the conversion process and allows you to handle complex JSON structures easily.
Some of the protocols you can use to customize mapping include:
– `EVReflectable`: Defines a custom mapping method.
– `EVCustomReflectable`: Provides a way to handle custom object mapping.
– `EVArrayConvertable`: Implements custom behavior for mapping arrays.
## Getting Started
To start using EVReflection in your project, follow these steps:
1. Install EVReflection through Swift Package Manager or Cocoapods.
2. Import the EVReflection module into your Swift file.
Here’s an example that demonstrates the installation process using Swift Package Manager:
“`swift
// Add the package dependency to your Package.swift file
dependencies: [
.package(url: “https://github.com/evermeer/EVReflection”, from: “4.1.0”)
],
targets: [
// Add the dependency to your target(s)
.target(name: “YourTarget”, dependencies: [“EVReflection”])
]
“`
Once you have installed EVReflection, you are ready to start using its powerful features in your Swift project.
## Usage Example
Let’s take a look at a simple example that demonstrates how to leverage EVReflection in your project.
Assume we have a JSON string that represents a user object:
“`json
{
“name”: “John Doe”,
“age”: 30,
“email”: “johndoe@example.com”
}
“`
To convert this JSON string into a Swift class instance, follow these steps:
1. Define a Swift class that represents the user object:
“`swift
class User: EVObject {
var name: String = “”
var age: Int = 0
var email: String = “”
}
“`
2. Convert the JSON string to a `User` object:
“`swift
let jsonString = “””
{
“name”: “John Doe”,
“age”: 30,
“email”: “johndoe@example.com”
}
“””
if let user = User(json: jsonString) {
// Successfully converted JSON to `User` object
}
“`
That’s it! You have successfully converted a JSON string into a `User` object using EVReflection.
## Conclusion
EVReflection is a powerful and lightweight library that simplifies working with JSON and Swift classes. It provides seamless JSON-to-Swift and Swift-to-JSON conversion, along with customizable mapping protocols. With EVReflection, you can save time and effort by eliminating manual JSON parsing code.
