Question 1

How to test AppDelegate with Pure DI?

Accepted Answer

Pure allows injecting mock dependencies into AppDelegate through a custom initializer, enabling unit testing of app lifecycle events. The README shows how to create a TestAppDelegate and use a main.swift file to separate environments for testing.

Question 2

Pure vs Swinject for iOS dependency injection

Accepted Answer

Pure is lightweight and promotes explicit DI without a container, ideal for testability and minimizing overhead. Swinject offers more features like auto-registration and scope management but adds framework complexity and potential performance trade-offs.

Question 3

How to inject dependencies in Storyboard view controllers with Pure

Accepted Answer

Use FactoryModule with customization to support Storyboard-instantiated view controllers. Extend the Factory type to instantiate from Storyboard and inject dependencies, as detailed in the Storyboard Support section of the README.

Question 4

Does Pure support SwiftUI?

Accepted Answer

Pure is designed for Cocoa applications (UIKit/AppKit) and might not directly integrate with SwiftUI's environment or dependency injection systems. It focuses on traditional MVC patterns, so adaptation for SwiftUI would require extra work.

Question 5

Best practices for lazy dependencies in Pure

Accepted Answer

Use FactoryModule for view controllers and ConfiguratorModule for cells to handle lazy creation and configuration. Define Dependency and Payload types to separate static and runtime information, as explained in the Lazy Dependency section.

Question 6

How to handle circular dependencies in Pure

Accepted Answer

Pure requires explicit manual composition, so circular dependencies must be resolved by refactoring or using techniques like lazy initialization or protocol abstraction within the Composition Root, as it doesn't provide automatic cycle detection.
