Mastering Swift 2 Programming (Video 8)

The video explores protocol oriented programming in Swift, highlighting its advantages over traditional inheritance. It discusses the differences between structs and classes, emphasizing the benefits of using protocols for code extensibility and reuse. The introduction of protocol extensions in Swift 2 is explained, showcasing how they allow for extending types and adding functionality without modifying individual subclasses. The video concludes with a brief overview of type constraints in protocol extensions and provides additional resources for further learning.

What is a major limitation of structs compared to classes in Swift?

• Structs are slower than classes.

• Structs cannot use inheritance.

• Structs cannot store data.

• Structs cannot have methods.

How do protocols help in making code more efficient compared to traditional inheritance?

• By enabling conformance only to needed functionalities.

• By requiring all functions to be implemented.

• By allowing multiple inheritance.

• By making classes larger and more complex.

What feature introduced in Swift 2 allows for extending entire types?

• Generics

• Optionals

• Protocol Extensions

• Type Inference

What is the purpose of using type constraints in protocol extensions?

• To prevent the use of generics.

• To allow inheritance in structs.

• To make the code run faster.

• To limit the extension to specific types.

What programming paradigm was introduced alongside functional programming in the video?

• Aspect-oriented programming

• Object-oriented programming

• Protocol oriented programming

• Procedural programming
