A UIViewController subclass for iOS/tvOS that manages child view controllers based on state, helping solve the Massive View Controller problem.
StateViewController is a container view controller for iOS and tvOS that presents different child view controllers based on defined states, such as loading, list, or editing. It manages child view controller lifecycles and state transitions, enabling modularization and reusability while staying within Apple's MVC pattern. This approach helps reduce view controller complexity without abandoning UIKit's primary design paradigm.
iOS and tvOS developers building complex view controllers who want to modularize their code and manage state-driven UI changes while adhering to Apple's MVC pattern. It's particularly useful for those dealing with the 'Massive View Controller' problem in UIKit-based apps.
Developers choose StateViewController because it provides a structured way to modularize view controllers and reduce complexity while maintaining full compatibility with UIKit's MVC pattern, avoiding the need to adopt alternative architectural patterns like MVVM or MVP. Its built-in lifecycle management and animated transition support offer a seamless way to handle state-based UI changes.

Presents child view controllers based on defined states like loading or ready, enabling modularization and reducing view controller complexity, as emphasized in the README's philosophy.
Manages view lifecycle events for child controllers during state transitions, ensuring proper appearance cycles and preventing common UIKit bugs, highlighted in the overview.
Supports animated transitions between states with control over duration and timing, demonstrated in the usage examples and protocol-based customization.
Works within Apple's MVC framework, providing a structured approach without abandoning UIKit's primary design pattern, a key selling point in the description.
Requires creating subclasses and overriding methods like loadAppearanceState() and children(for:), adding boilerplate code and complexity for simple use cases.
Only available via Carthage, as per the README, which may not align with teams using CocoaPods or Swift Package Manager, creating dependency management hurdles.
Developers must explicitly handle state transitions and callbacks using setNeedsTransition(to:animated:), increasing the risk of errors in complex state flows.
