Start Developing iOS Apps (Swift) is the perfect starting point for learning to create apps that run on iPhone and iPad. View this set of incremental lessons as a guided introduction to building your first app—including the tools, major concepts, and best practices that will ease your path.
Each lesson contains a tutorial and the conceptual information you need to complete it. The lessons build on each other, walking you through a step-by-step process of creating a simple, real-world iOS app.
As you make your way through the lessons and build the app, you’ll learn about concepts in iOS app development, gain a deeper understanding of the Swift programming language, and familiarize yourself with the many valuable features of Xcode, Apple’s integrated development environment (IDE).
1. Download xCode
Download the latest version of Xcode on your Mac free from the App Store. Scroll down and check how to download xCode on your system.
2. Create a New Project
Xcode includes several built-in app templates for developing common types of iOS apps, such as games, apps with tab-based navigation, and table view-based apps.
3. Learn Swift Language
Swift is a fantastic way to write software, whether it’s for phones, desktops, servers, or anything else that runs code.
Steps For Downloading xCode
Open the App Store app on your Mac (by default it’s in the Dock).
In the search field in the top-right corner, type Xcode and press the Return key. The Xcode app shows up as the first search result.
Click Get and then click Install App.
Enter your Apple ID and password when prompted.
Xcode is downloaded into your /Applications directory.
Steps For Create a New Project
Open Xcode from the /Applications directory.
If this is the first time you’ve launched Xcode, it may ask you to agree to the user agreement and to download additional components. Follow the prompts through these screens until Xcode is completely set up and ready to launch.
As soon as Xcode launches, the welcome window appears.
If a project window appears instead of the welcome window, don’t worry—you probably created or opened a project in Xcode previously. Just use the menu item in the next step to create the project.
In the welcome window, click “Create a new Xcode project” (or choose File > New > Project).
Xcode opens a new window and displays a dialog in which you choose a template.
Select iOS at the top of the dialog.<
In the Application section, select Single View Application and then click Next.
In the dialog that appears, use the following values to name your app and choose additional options for your project:
Product Name: FoodTracker Xcode uses the product name you entered to name your project and the app.
Team: If this is not automatically filled in, set the team to None.
Organization Name: The name of your organization or your own name. You can leave this blank.
Organization Identifier: Your organization identifier, if you have one. If you don’t, use com.example.
Bundle Identifier: This value is automatically generated based on your product name and organization identifier.
A Universal app is one that runs on both iPhone and iPad.
Swift is a fantastic way to write software, whether it’s for phones, desktops, servers, or anything else that runs code. It’s a safe, fast, and interactive programming language that combines the best in modern language thinking with wisdom from the wider Apple engineering culture and the diverse contributions from its open-source community. The compiler is optimized for performance and the language is optimized for development, without compromising on either.
Swift is friendly to new programmers. It’s an industrial-quality programming language that’s as expressive and enjoyable as a scripting language. Writing Swift code in a playground lets you experiment with code and see the results immediately, without the overhead of building and running an app.
Swift defines away large classes of common programming errors by adopting modern programming patterns:
Variables are always initialized before use.
Array indices are checked for out-of-bounds errors.
Integers are checked for overflow.
Optionals ensure that nil values are handled explicitly.
Memory is managed automatically.
Error handling allows controlled recovery from unexpected failures.
Swift has been years in the making, and it continues to evolve with new features and capabilities. Our goals for Swift are ambitious. We can’t wait to see what you create with it. Learn More About Swift Language
