*Transformers* is a framework to transform things elegantly using the power of Swift programming language.
> Note: Support Swift version: 4.1 or newer
## Feature
- Cast JSON data with type.
- Cast a swift dictionary to swift model which confirms `Codable` protocol.
- Cast a swift array whose item type is dictionary to swift model array whose items confirm `Codable` protocol.
## Installation
### Manual
Download the project, and drag the `Core` folder to your project.
### Carthage
Add this to `Cartfile`
```
github "webfrogs/Transformers" ~> 1.0
```
### Swift Package Manager
```
dependencies: [
.package(url: "https://github.com/webfrogs/Transformers.git", .upToNextMinor(from: "1.0.0")),
]
```
## Usage
The most common scene in iOS programming is handle JSON data.
### Handle JSON
```swift
let jsonString = """
{"key1": "value2"}
"""
let value1: String? = jsonString.data(using: String.Encoding.utf8)
.flatMap({$0.toDictionary()})
.flatMap({$0.value(key: "key1")})
print(value1 ?? "")
```
### RxSwift
If you also use [RxSwift](https://github.com/ReactiveX/RxSwift) in your project. *Transformers* can be easily integrated with RxSwift, and there is no need to transform JSON data fetched from http server to a model manually. All you have to do is define a model which confirms *Codable* protocol and use *Transformers* with the *map* function provided by RxSwift.
Here is a demo code:
```swift
struct GithubAPIResult: Codable {
let userUrl: String
let issueUrl: String
enum CodingKeys: String, CodingKey {
case userUrl = "user_url"
case issueUrl = "issues_url"
}
}
let request = URLRequest(url: URL(string: "https://api.github.com")!)
let apiResult: Observable = URLSession.shared
.rx.data(request: request)
.map(Data.jsonToModelHandler)
apiResult.subscribe(onNext: { (result) in
print(result)
}).disposed(by: kDisposeBag)
```
