🔵 The Bridge Pattern in Swift​

The Bridge Pattern is a structural design pattern that separates an object’s abstraction from its implementation, enabling both to evolve independently. It is especially valuable in Swift for managing complex systems with multiple variations and avoiding tightly coupled hierarchies.

Key Points​

  • Definition: Separates abstraction from implementation, allowing independent evolution of both.
  • Use Cases: Avoids subclass explosion, supports extensibility, and simplifies complex systems.
  • Applicability: Ideal when abstraction and implementation need independent variation.
  • Relationships: Complements patterns like Adapter, Decorator, and Composite.

Summary of Contents​

  • Introduction: Explanation of the Bridge Pattern and its significance in Swift.
  • Conceptual Example: Shapes and rendering mechanisms demonstrating abstraction-implementation decoupling.
  • Real-World Applications: Graphical libraries managing shapes and rendering methods independently.
  • Pseudocode: Protocol-based Swift example with Shape and Color hierarchies.
  • Implementation Steps:
    • Identify aspects for independent variation.
    • Define protocols for abstraction and implementation.
    • Create concrete classes for abstraction and implementation.
    • Establish the bridge through a reference in the abstraction.
  • Pros and Cons: Highlights advantages like extensibility and disadvantages like added complexity.
  • Pattern Relationships: Comparisons and synergies with Adapter, Decorator, and Composite patterns.

🔵 The Proxy Pattern in Swift​

The Proxy Pattern is a structural design pattern that acts as a placeholder or surrogate for another object, enabling control over access to the original object. It supports functionality like lazy loading, access control, and logging without altering the core object’s code.

Tags:
design-patterns, swift, ios-development, proxy-pattern, lazy-loading

Key Points​

  • Definition: Provides a surrogate or placeholder to control access to another object.
  • Use Cases: Commonly used for lazy loading, access control, and adding logging or monitoring.
  • Advantages: Improves performance, enables controlled access, and supports instrumentation.
  • Disadvantages: Adds complexity, potential indirection overhead, and risks of overuse.
  • Relationships: Similar to the Decorator Pattern but focuses on access control. Can be used with Adapter and Singleton patterns.

Summary of Contents​

  • Introduction: Explanation of the Proxy Pattern and its purpose in Swift development.
  • Conceptual Example: Proxy for image loading to delay expensive operations until required.
  • Real-World Applications: Cloud storage proxies representing remote files to save bandwidth and storage.
  • Implementation Steps: A step-by-step guide to creating proxies for managing access and functionality.
  • Code Examples: Example implementation of an ImageProxy that provides lazy initialization for image loading.
  • Pros and Cons: Highlights the benefits and trade-offs of using the Proxy Pattern.
  • Pattern Relationships: Discusses similarities and synergies with other design patterns like Decorator and Adapter.
