Chapter 12: Best Practices

Questions:

1. Why would you want to develop a library for your application?
2. What is the advantage of protocols in Swift?
3. How can generic functions help you?
4. How do Xcode and lldb help you debug?

Answers:

1. Because you might have classes that you want to share across microservices.
2. You can define what you want types to have and what they look like without dictating the type itself.
3. They can cover a number of types, and therefore reduce work.
4. They help you find the exact line in which errors occurred.
