2. Getting Started
Before we begin building our GVCourse app, let's ensure your development environment is set up correctly.
SwiftUI requires macOS 10.15 Catalina or later. To check your macOS version, click the Apple icon in the top left corner of your screen and select About This Mac.
Install the latest version of Xcode from the Mac App Store.
Simulator is a tool that allows you to run your app on a virtual device. To open Simulator, open Xcode and select Xcode > Open Developer Tool > Simulator.
SF Symbols is a set of over 3,100 symbols that you can use in your app. To install SF Symbols, open Xcode and select File > Swift Packages > Add Package Dependency. In the search bar, type "SF Symbols" and click Next. Select the latest version and click Next. Finally, click Finish.
In this tutorial, we will use SF Symbols to display icons in our app. For example, we will use the following code snippet to display a user icon:
Image(systemName: "person.circle")
