Swift
A powerful and easy to learn programming language.
About ## Swiftj
Swift is a powerful and intuitive programming language that works on all Apple platforms. Swift's syntax is simple but expressive, and it includes much loved modern features that are easy to use. Swift code is designed to be secure and create software that runs as fast as lightning.
Modernization
Swift is the latest in programming language research and incorporates decades of experience building Apple platforms. Named parameters are expressed in a concise syntax that makes it easier to read and maintain apis written in Swift. You don't even have to type a semicolon. Inferred types make code cleaner and less prone to error; Modules, on the other hand, eliminate header files and provide namespaces instead. To provide optimal support for multiple languages and emoji, strings are Unicode correct and use UTF-8-based encodings to optimize performance in a variety of use cases. Memory is automatically managed with a rigorous deterministic reference count, minimizing memory usage and incurring no garbage collection overhead. You can even write concurrent code using simple built-in keywords that define asynchronous behavior, making the code cleaner, easier to read, and less prone to errors.
Ensure safety by design
Swift avoids all types of insecure code. Variables are always initialized before use, arrays and integers are checked for overflow, memory is automatically managed, and mandatory exclusive access to memory protects against many programming errors. The syntax has been tweaked to make it easy to define goal intent. For example, a three-character keyword can define a variable (var) or a constant (let). In addition, Swift takes full advantage of value types, especially for common types such as Array and Dictionary. This allows you to copy this type of content with the confidence that it will not be modified elsewhere.
By default, Swift objects cannot be set to nil - this, on the other hand, ensures Swift's security. In fact, the Swift compiler displays compile-time errors when you try to create or use nil objects, preventing you from continuing. This makes writing code cleaner and safer, and prevents a very common type of runtime crash for apps. However, in some cases, nil is appropriate and justified. For these types of situations, Swift offers an innovative feature called "Optional Types." The optional type can contain nil, but Swift syntax forces you to use? Syntax to safely handle nil. By using this syntax, you show the compiler that you understand the behavior and will handle it safely.
Fast and powerful
When we first conceived it, we wanted Swift to be fast. Using the outstanding high-performance LLVM compiler technology, Swift code is transformed into machine code optimized to take full advantage of modern hardware. In addition, the syntax and standard libraries have been tweaked so that even the most obvious coding can perform best, whether it's running on a watch on your wrist or between clustered servers.
Swift is a new programming language developed on the basis of C, C++ and Objective-C. It contains underlying primitives such as types, flow controls, and operators. In addition, it provides object-oriented features such as classes, protocols, and generics, giving Cocoa and Cocoa Touch developers the performance and functionality they need.
Open source
Swift is developed as open source on Swift.org, and its source code, bug management, forums, and general development versions will be available to everyone. Within this broad community of developers, Apple employees work with hundreds of external contributors to make Swift even better. There will also be more blogs, podcasts, conferences and gatherings for developers in the community to share their experiences on how to harness Swift's potential.
cross-platform Swift already supports all Apple platforms and Linux, and community members are actively working to port Swift to more platforms. With SourceKit-LSP, community members are also working to integrate Swift support into various developer tools. We're excited to see Swift build more secure and faster software in more diverse ways, while also making programming more fun."
Swift is for servers Swift is not only capable of developing many new apps for Apple platforms, but also works with a new range of modern server apps. Swift is ideal for server apps that require runtime security, compile performance, and a small memory footprint. In order to navigate the direction of developing and deploying Server apps using Swift, the Swift community formed the Swift Server Working Group. The group's first product for this purpose is SwiftNIO, a cross-platform, asynchronous, event-driven web App framework for high-performance protocol servers and clients. It is the foundation on which other server-oriented tools and technologies are built, including logging, metrics, and database drivers that are under active development.
