Swift code coexists along side your existing Objective-C and C++ files in the same project, with access to your Objective-C and C++ APIs, making it easy to adopt. It includes low-level primitives such as types, flow control, and operators. It also provides object-oriented features such as classes, protocols, and generics. Provide default values for instance properties and define custom initializers.

Another safety feature is that by default Swift objects can never be nil. In fact, the Swift compiler will stop you from trying to make or use a nil object with a compile-time error. This makes writing code much cleaner and safer, and prevents a huge category of runtime crashes in your apps. For these situations Swift has an innovative feature known as optionals. An optional may contain nil, but Swift syntax ensures you to safely deal with it using the ? Syntax to indicate to the compiler you understand the behavior and will handle it safely.
Open source
- Swift is developed in the open at Swift.org, with source code, a bug tracker, forums, and regular development builds available for everyone.
- It also provides object-oriented features such as classes, protocols, and generics.
- Using the incredibly high-performance LLVM compiler technology, Swift code is transformed into optimized machine code that gets the most out of modern hardware.
- If you’re an educator and would like to bring app development with Swift into your classroom, check out the Develop in Swift Tutorials Educator Guide.
- It’s perfect for use in server apps that need runtime safety, compiled performance, and a small memory footprint.
- The result view can display graphics, lists of results, or graphs of a value over time.
If you’re an educator and would like to bring app development with Swift into your classroom, check out the Develop in Swift Tutorials Educator Guide. Start your app development journey by getting to know Xcode, Swift, and SwiftUI. Download Xcode and learn how to build apps using Swift with documentation and sample code. Add functionality to existing types using extensions, and cut down on boilerplate code with custom string interpolations.

- Syntax is tuned to make it easy to define your intent — for example, simple three-character keywords define a variable ( var ) or constant ( let ).
- The first product of this effort was SwiftNIO, a cross-platform asynchronous event-driven network application framework for high performance protocol servers and clients.
- Inferred types make code cleaner and less prone to mistakes, while modules eliminate headers and provide namespaces.
- Configuration of packages is written in Swift itself, making it easy to configure targets, declare products, and manage package dependencies.
Swift
And Swift heavily leverages value types, especially for commonly used types like Arrays and Dictionaries. This means that when you make a copy of something with that type, you know it won’t be modified elsewhere. Swift 6 makes it easier to write concurrent code correctly with a new, optional language mode that analyzes your code at compile-time and diagnoses possible data races. This release also brings other enhancements to concurrency and generics, as well as improved support for source editors that use the Language Server Protocol.
- Swift is the result of the latest research on programming languages, combined with decades of experience building software that runs on billions of devices.
- To steer the direction of Swift for developing and deploying server applications, the community formed the Swift Server work group.
- Swift packages can also include custom commands that help build your projects and provide additional tooling.
- Swift already supports all Apple platforms, Linux, and Windows, with community members actively working to port to even more platforms.
- Quickly extend your custom types to take advantage of powerful language features, such as automatic JSON encoding and decoding.
- Swift 6 makes it easier to write concurrent code correctly with a new, optional language mode that analyzes your code at compile-time and diagnoses possible data races.
Objective-C and C++ interoperability
It serves as the foundation for additional server-oriented tools and technologies, including logging, metrics, and database drivers. In fact, it was designed to be anyone’s first programming Swift developer job language, whether you’re still in school or exploring new career paths. For educators, Apple created free curriculum to teach Swift both in and out of the classroom. First-time coders can download Swift Playgrounds — an app for iPad and Mac that makes getting started with Swift code interactive and fun. Swift is a powerful and intuitive programming language for all Apple platforms.
