Your apps will leverage the latest version of the library in the OS, and your code will continue to run without recompiling.Writing Swift code is interactive and fun, the syntax is concise yet expressive, and Swift includes modern features developers love.
Alawar Games Software That RunsSwift code is safe by design, yet also produces software that runs lightning-fast.
Alawar Games Code Will ContinueInferred types make code cleaner and less prone to mistakes, while modules eliminate headers and provide namespaces. To best support international languages and emoji, Strings are Unicode-correct and use a UTF-8 based encoding to optimize performance for a wide-variety of use cases. Memory is managed automatically using tight, deterministic reference counting, keeping memory usage to a minimum without the overhead of garbage collection. Provide default values for instance properties and define custom initializers. ![]() Syntax is tuned to make it easy to define your intent for example, simple three-character keywords define a variable ( var ) or constant ( let ). 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 wont be modified elsewhere. 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 forces you to safely deal with it using the syntax to indicate to the compiler you understand the behavior and will handle it safely. Using the incredibly high-performance LLVM compiler technology, Swift code is transformed into optimized native code that gets the most out of modern hardware. The syntax and standard library have also been tuned to make the most obvious way to write your code also perform the best whether it runs in the watch on your wrist or across a cluster of servers. It includes low-level primitives such as types, flow control, and operators. It also provides object-oriented features such as classes, protocols, and generics, giving Cocoa and Cocoa Touch developers the performance and power they demand. In fact, it was designed to be anyones first programming language, whether youre still in school or exploring new career paths. ![]() Alawar Games Download Swift PlaygroundsanFirst-time coders can download Swift Playgroundsan app for iPad that makes getting started with Swift code interactive and fun. And Apple Stores around the world host Today at Apple Coding Apps sessions where you can get hands-on experience with Swift code. Instead you can start using the new compiler and migrate at your own pace, taking advantage of new Swift 5 features, one module at a time. That means you no longer need to include Swift libraries in apps that target current and future OS releases, because the Swift libraries will be included in every OS release going forward.
