Message Forwarding vs Static Dispatch

Developers should learn message forwarding when working with dynamic languages like Objective-C or Swift to implement advanced patterns like proxy objects, where one object stands in for another to control access or add functionality meets developers should use static dispatch when performance is critical, as it eliminates runtime overhead associated with virtual method tables or dynamic lookups, making it ideal for systems programming, embedded systems, and high-performance computing. Here's our take.

Message Forwarding

Nice Pick

Developers should learn message forwarding when working with dynamic languages like Objective-C or Swift to implement advanced patterns like proxy objects, where one object stands in for another to control access or add functionality

Pros

• It's essential for building flexible architectures, such as in iOS/macOS development for handling unimplemented methods dynamically, enabling features like method interception or creating adaptable components that can respond to unknown messages at runtime
• Related to: objective-c, swift

Cons

• Specific tradeoffs depend on your use case

Static Dispatch

Developers should use static dispatch when performance is critical, as it eliminates runtime overhead associated with virtual method tables or dynamic lookups, making it ideal for systems programming, embedded systems, and high-performance computing

Pros

• It is particularly useful in languages like C++ with templates or Rust with monomorphization, where compile-time type checking ensures safety and efficiency
• Related to: polymorphism, c-plus-plus-templates

Cons

• Specific tradeoffs depend on your use case

The Verdict

Use Message Forwarding if: You want it's essential for building flexible architectures, such as in ios/macos development for handling unimplemented methods dynamically, enabling features like method interception or creating adaptable components that can respond to unknown messages at runtime and can live with specific tradeoffs depend on your use case.

Use Static Dispatch if: You prioritize it is particularly useful in languages like c++ with templates or rust with monomorphization, where compile-time type checking ensures safety and efficiency over what Message Forwarding offers.

The Bottom Line

Message Forwarding wins

Developers should learn message forwarding when working with dynamic languages like Objective-C or Swift to implement advanced patterns like proxy objects, where one object stands in for another to control access or add functionality
