Dependency Injection Setup

Instructions

Add new services to Leavn's DIContainer:

Create service protocol:

// Services/MyDomain/MyServiceProtocol.swift
public protocol MyServiceProtocol {
    func doSomething() async throws -> Result
}

Create implementation:

// Services/MyDomain/MyServiceLive.swift
public final class MyServiceLive: MyServiceProtocol {
    public init() { }

    public func doSomething() async throws -> Result {
        // Implementation
    }
}

Register in DIContainer:

// For singletons (stateful services):
private lazy var _myService = MyServiceLive()
var myService: MyServiceProtocol {
    _myService
}

// For factories (stateless services):
var myService: MyServiceProtocol {
    MyServiceLive()
}

Use in ViewModels:

let service = DIContainer.shared.myService

Use this skill when: Creating new service, adding dependency, setting up DI, refactoring to protocol-oriented design
