Swift: Introduction to Arrays

Introduction to Arrays in Swift:

Before getting into actual coding, let’s have a brief introduction to arrays in Swift. We live in a world that is becoming increasingly connected, with information flowing between us and the apps we use on daily basis. Previously, the information was kept in filing cabinets, but nowadays, the majority of it is kept on computers.

When we write programs that collect data about our surroundings, we will need to store data collections. For instance, we might need to keep:

  • Names of attendees of zoom meeting.
  • List of orders on amazon.
  • Hashtag list on Instagram.

We know how to store a single piece of data in an Int, Double, or String variable, but what about a group of Int, Double, or String? This is where arrays come in handy.

An array is a collection of values that are stored in a specific order.

We’ll learn how to create and use an array, as well as some of its properties and methods further in this lesson.

Helpful Tools:

Here are some useful tools to help you along your journey!

Setting up an IDE (Integrated Development Environment) can be difficult for beginners. The Online Compiler will enable you to run your code inside your browser without the need to install an IDE. If you need a more detailed explanation of a specific topic, the best place to find answers is in the Official Documentation.
