How does this skill improve app testability?

It provides standardized templates for protocol-oriented programming, allowing you to easily swap production services for mock implementations during unit testing.

Which dependency injection patterns are supported?

The skill covers constructor injection, protocol-based DI, SwiftUI Environment injection, DI Containers, and the Factory pattern.

Is this skill specific to SwiftUI?

While it includes specialized patterns for SwiftUI (like EnvironmentObject), the core DI and container patterns are applicable to UIKit and general Swift development.

Does it support tvOS development?

Yes, all patterns provided are fully compatible with both iOS and tvOS platforms.

Implements robust dependency injection patterns for iOS and tvOS applications using Swift and SwiftUI best practices.

Acerca de

This skill provides comprehensive guidance and implementation patterns for Dependency Injection (DI) within the Apple ecosystem. It bridges the gap between traditional architectural patterns like constructor injection and modern SwiftUI-native approaches using Environment Objects and custom Keys. By leveraging protocol-oriented programming and DI containers, this skill helps developers create modular, loosely coupled codebases that are significantly easier to test, maintain, and scale in enterprise-grade environments.
