  • Control Flow: Conditional statements like if, else, and loops like for and while are crucial for controlling the execution of code based on certain conditions.
  • Functions: Functions encapsulate reusable code. They can take inputs (parameters) and return outputs (return values).

Key Swift Features

Swift is designed with a strong emphasis on safety, performance, and expressiveness, which ensures fewer runtime errors and better readability.

  1. Optionals: Swift uses optionals to handle cases where a value might be absent. An optional can either hold a value or be nil.
  2. Closures: Closures are self-contained blocks of functionality that can be passed around and used in your code. They are similar to functions but can capture and store references to variables and constants.
  3. Protocols: A protocol defines a blueprint of methods and properties that can be adopted by classes, structures, and enums. This is used for creating reusable and flexible components.

Swift Data Structures

Data Structure Description
Arrays A collection of values ordered by index.
Dictionaries A collection of key-value pairs.
Sets An unordered collection of unique values.
