#14 Swift Programming - Arithmetic Operators

Welcome to Lesson 14 of our Learn Swift with David series! Today, we delve into the essentials of arithmetic operators in Swift. This topic is fundamental for anyone starting out with Swift, as arithmetic operators are used in virtually every application to perform basic calculations, manipulate data, and control logic flows. Whether you're developing for iOS, macOS, or any other platform supported by Swift, having a solid grasp of how to use these operators is crucial.

In Swift, arithmetic operators are not just tools for simple calculations but also the building blocks for more complex algorithms and functionalities. Swift supports all the basic arithmetic operators that you might be familiar with from mathematics: addition (`+`), subtraction (`-`), multiplication (`*`), division (`/`), and modulus (`%`).

In this lesson, David will start by explaining each of the arithmetic operators, providing the syntax and basic usage examples. You'll learn how to use these operators to add, subtract, multiply, and divide values. A special focus will be given to the modulus operator, which might be less familiar but is incredibly useful for determining remainders in division operations.

Following the basics, David will dive deeper into how these operators can be used in real-world programming scenarios. This includes performing operations on variables, using arithmetic to control loops and conditional statements, and combining operators with assignment for efficient coding (e.g., `+=`, `-=`, `*=`, `/=`).

Moreover, this lesson will cover best practices when using arithmetic operators in Swift, such as handling division by zero and working with different data types (e.g., integers vs. floating-point numbers). Swift's type safety features help prevent common errors in arithmetic operations, and David will explain how to leverage these features to write safer and more reliable code.

To ensure you fully understand these concepts, David will provide practical examples and exercises that you can follow along with in an Xcode playground. These exercises are designed to reinforce the concepts discussed by applying them in coding tasks that simulate real-world applications.
