## Simple dependency injection library using Swift property wrappers
Tired of creating a lot of property on initializers of your classes so it's easier to test them? With **Vaccine** is possible to define properties in your classes using `@propertyWrapper`s in a very simple way!
## Installation
### Swift Package Manager
In **Xcode** go to `File->Swift Packages->Add Package Dependency...` and paste the url:
`https://github.com/munirwanis/Vaccine.git`
If you are adding this package as a dependency to another package, paste this on your `Package.swift` file:
```swift
dependencies: [
.package(url: "https://github.com/munirwanis/Vaccine.git", .upToNextMajor(from: "1.0.0" )),
]
```
### Manual
Since this project has no dependencies, it's possible to drag the source files to your project.
### Other package managers
If manual or SPM are not a option, pull requests will be very welcome to help support other platforms.
## Compatibility
- [X] **Swift 5.1+**
- [X] **Xcode 11+**
## Usage
### Register dependencies
You can use the starting point of your application to register the dependencies that will be resolved later. Let's say we have a protocol for a service called `SomeServiceProtol`, and I want to resolve it with my class `SomeService`.
```swift
import Foundation
import Vaccine
@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {
func application(_ application: UIApplication,
configurationForConnecting connectingSceneSession: UISceneSession,
options: UIScene.ConnectionOptions) -> UISceneConfiguration {
// Registers the dependency for my service
Vaccine.setCure(for: SomeServiceProtocol.self, with: SomeService())
return UISceneConfiguration(name: "Default Configuration", sessionRole: connectingSceneSession.role)
}
}
```
You can also set the property `isUnique` to `true` to ensure that the object injected is singleton.
```swift
Vaccine.setCure(for: SomeServiceProtocol.self, isUnique: true, with: SomeService())
```
If your object needs to do some complex things you can also pass the resolver as a closure, like this:
```swift
// Can also use `isUnique` property
Vaccine.setCure(for: SomeServiceProtocol.self) {
let item = ["Hello", "World"].randomElement() ?? ""
return SomeService(text: item)
}
```
### Resolve dependencies
To resolve dependencies is pretty simple, simply use `@Inject` property wrapper inside your class:
```swift
class SomeViewModel {
// Will instantiate or get an already instantiated (if singleton) version of `SomeService`
@Inject(SomeServiceProtocol.self) var service
func getText() -> String {
service.getText()
}
}
```
