# pilgrim.ph
Pilgrim is a dependency injection library for Swift with the following features:
* Minimal runtime-only library that works with pure Swift (structs, classes, protocols) as well as ObjC base classes, when necessary.
* Easy to install. Works on iOS, Mac & Linux. No compile-time weaving required.
* Type safe. No reflection or ObjC runtime, because it is pure swift. (Uses higher-order functions.)
* Lifecycles management: `shared`, `weakShared`, `objectGraph` (a DI concept introduced by [Typhoon](https://github.com/appsquickly/typhoon), for desktop and pocket apps) & `unshared`.
* Can be used with SwiftUI, UIKit and Cocoa based apps.
* Simple and flexible. For example, it is easy to have two injectable instances that conform to the same protocol.
* Provides the notion of a [composition root](https://freecontent.manning.com/dependency-injection-in-net-2nd-edition-understanding-the-composition-root/) in which the key actors, and their interactions in an application architecture are defined as a graph. This is where your app's architectural story is told. Assembled instances can then be injected into top level classes, such as a view controller, in a UIKit app, using property wrappers.
* Runtime args. Can act as a factory for emitting new instances derived from a mix of runtime parameters and key architectural actors.
* **Official successor to [Typhoon](https://github.com/appsquickly/typhoon) and based on the excellent [FieryCrucible](https://github.com/jkolb/FieryCrucible) by [jkolb](https://github.com/jkolb).**
You can use Pilgrim in apps that employ the object-oriented programming paradigm or that mix object-oriented and functional styles.
---------------------------------------
## Quick Start
Want to start applying dependency injection to your code in two minutes? **Follow the [Quick Start](https://github.com/appsquickly/pilgrim/wiki) guide!**
```swift
class AppDelegate: UIResponder, UIApplicationDelegate {
@Assembled var assembly: ApplicationAssembly
@Assembled var cityRepo: CityRepository
@Assembled var rootViewController: RootViewController
var window: UIWindow?
func application(_ application: UIApplication,
didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]? = nil) -> Bool {
window = assembly.window()
window?.makeKeyAndVisible()
if (cityRepo.loadSelectedCity() == nil) {
rootViewController.showCitiesListController()
}
return true
}
}
```
_Here's how your code might look, when you're done with the [quick start](https://github.com/appsquickly/pilgrim/wiki)._
## Installation
### CocoaPods
```
pod 'Pilgrim-DI'
```
Other installation methods (Swift Package Manager, etc) coming soon!
