What objects are involved in dependencies in a project?

In iOS projects, the following objects are usually involved in dependencies:

• Frameworks and libraries — external or internal modules that provide functionality (e.g., Alamofire, Realm).
• Application modules — separate components or layers that depend on each other (e.g., the business logic layer depends on the data layer).
• Services and managers — objects that provide access to APIs, databases, settings, etc.
• Protocols (interfaces) — for dependency inversion and easing testing.

Dependency management is achieved through:

• Dependency Injection — passing dependencies via initializers or properties.
• Package Managers — CocoaPods, Carthage, Swift Package Manager for external libraries.

Thus, objects involved in dependencies are those used or injected to ensure functionality and interaction between application components.
