Build Swift

Swift is a modern and intuitive programming language that ranks among the top programming languages for mobile app development. 

Originally developed by Apple, Swift is now the recommended programming language for developing apps for all Apple platforms including iOS, iPadOS, macOS, tvOS, and watchOS. If you plan to write an app for an Apple device, you will need to learn to program in Swift.

In this course, you will cover topics ranging from basic data types, constants and variables, arrays, dictionaries, object-oriented programming, logic and control flow, file and file system management, and error handling.

On completion of this course, you will have sufficient foundational knowledge of Swift programming to begin learning other areas of Apple-based app development such as SwiftUI.

Swift Programming for Mobile App Development

Apps for Apple's family of device platforms are developed using the Xcode development environment. Xcode is an integrated development environment (IDE) within which you will code, compile, test, and debug your applications.

In this lesson, we will cover the steps involved in installing Xcode on macOS. 

# Installing Xcode 

The best way to obtain the latest versions of Xcode is to download it from the Apple Mac App Store. Launch the App Store on your macOS system, enter Xcode into the search box and click on the *Get* button to initiate the installation. This will install both Xcode and the iOS SDK.

# Starting Xcode

Having successfully installed Xcode, the next step is to launch it so that we are ready to start development work. To start up Xcode, open the macOS Finder and search for Xcode. Since you will be making frequent use of this tool, take this opportunity to drag and drop it onto your dock for easier access in the future. Click on the Xcode icon in the dock to launch the tool. The first time Xcode runs you may be prompted to install additional components. Follow these steps, entering your username and password when prompted to do so.

Once Xcode has loaded and assuming this is the first time you have used Xcode on this system, you will be presented with the Welcome screen from which you are ready to proceed:
