dependency injection setup

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
}

}

// 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
