How to Build iPhone Apps on Mac Using Swift and Xcode
If you want to create amazing apps for iOS, Mac, Apple TV, and Apple Watch, you need to learn Swift and Xcode. Swift is a powerful and intuitive programming language created by Apple that lets you write safer, more reliable code, and get real-time feedback. Xcode is the Mac app that you use to build every other Mac app and every iOS app, too. It has all the tools you need to design, develop, and debug your app.
In this article, we will show you how to get started with Swift and Xcode, and how to build a simple iPhone app that displays a list of earthquakes from a real-world data source. You will learn how to:
Set up your development environment and create a new project.
Use the Swift Package Manager to add dependencies to your project.
Decode structured JSON data using the Codable protocol.
Display data in a table view using SwiftUI.
Run and test your app on a simulator or a real device.
Let's get started!
Set up your development environment and create a new project
To build iPhone apps on Mac, you need to have Xcode installed on your machine. Xcode is available as a free download from the Mac App Store. You can also download it from the Apple Developer website if you have an Apple Developer account.
Once you have Xcode installed, launch it and create a new project. Choose iOS as the platform, and select App as the template. Click Next to continue.
On the next screen, enter a name for your project, such as Earthquakes. Choose SwiftUI as the interface, SwiftUI App as the lifecycle, and Swift as the language. You can also choose an organization name and identifier for your app. Click Next to continue.
On the final screen, choose a location to save your project. You can also check the Create Git repository option if you want to use version control for your code. Click Create to finish.
Xcode will create a new project for you and open it in the project window. You will see a file called ContentView.swift in the Project navigator on the left. This is where you will write your SwiftUI code to create the user interface for your app.
Use the Swift Package Manager to add dependencies to your project
To display earthquake data in your app, you will need to fetch it from a web service that provides JSON data. For this tutorial, we will use the USGS Earthquake Hazards Program API (https://earthquake.usgs.gov/fdsnws/event/1/), which provides information about earthquakes around the world.
To make network requests and decode JSON data in Swift, you will need to use some external libraries. One of the easiest ways to add dependencies to your project is to use the Swift Package Manager (SPM), which is integrated with Xcode. SPM is a tool that lets you manage Swift packages, which are collections of code that can be reused across projects.
To add dependencies using SPM, go to File > Swift Packages > Add Package Dependency. In the search field, enter https://github.com/Alamofire/Alamofire.git and click Next. Alamofire is a popular library that simplifies network requests in Swift. On the next screen, choose the latest version of Alamofire and click Next. Xcode will download and install Alamofire for you.
Repeat the same steps to add another dependency: https://github.com/SwiftyJSON/SwiftyJSON.git. SwiftyJSON is a library that makes it easy to work with JSON data in Swift.
After adding both dependencies, you will see them listed under Swift Packages in the Project navigator. You can also see them under Frameworks, Libraries, and Embedded Content in the General tab of your project settings.
Decode structured JSON data using the Codable protocol
To display earthquake data in your app, you will need to define a data model that represents an earthquake. In Swift, you can use structs or classes to define custom types that conform to the Codable protocol. The Codable protocol allows you to encode and decode data between different formats, such as JSON.
