Dependency Injection Setup

Instructions

Add new services to Leavn's DIContainer:

1. Create service protocol:

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

2. Create implementation:

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

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

}

3. **Register in DIContainer**:
```swift
// For singletons (stateful services):
private lazy var _myService = MyServiceLive()
var myService: MyServiceProtocol {
    _myService
}

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

1. 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
