What is a function in programming?

A function is a named block of code that you can execute on demand by calling its name.

Why does Swift have optionals?

Why do Swift even have optionals? Well, Swift is a type-safe language so it forces you to specify the exact data types you’re working with at every point in your program. In the long run, this helps tremendously by forcing you to think of things such as whether a variable will ever need to be empty or always contain a value. Swift’s type-safety also prevents you from accidentally storing different kinds of data from what you intended in a variable.

How does Swift work?

Swift eliminates entire classes of unsafe code. Variables are always initialized before use, arrays and integers are checked for overflow, memory is automatically managed, and enforcement of exclusive access to memory guards against many programming mistakes. Syntax is tuned to make it easy to define your intent — for example, simple three-character keywords define a variable ( var ) or constant ( let ). And Swift heavily leverages value types, especially for commonly used types like Arrays and Dictionaries. This means that when you make a copy of something with that type, you know it won’t be modified elsewhere.
