The Swift Programming Language Book
The Swift standard library defines a base layer of functionality for writing Swift programs. Documentation for the standard library is presently hosted on the Apple Developer website.
There are a number of packages that are part of the core Swift project. Below is a list of packages that currently offer hosted documentation.
Delivering a clear, consistent developer experience when writing Swift code is largely defined by the names and idioms that appear in APIs. These design guidelines explain how to make sure that your code feels like a part of the larger Swift ecosystem.
Not only are optionals safer and more expressive than nil pointers in Objective-C, they’re at the heart of many of Swift’s most powerful features. Swift is a type-safe language, which means the language helps you to be clear about the types of values your code can work with.
Swift is intended to be easy to start learning, but to scale so that it can be used to develop large, high performance, complicated applications. It has a friendly, approachable syntax, and a lot of features that make it an ideal programming language for the practical work of building mobile applications.
Swift combines powerful type inference and pattern matching with a modern, lightweight syntax, allowing complex ideas to be expressed in a clear and concise manner. As a result, code is not just easier to write, but easier to read and maintain as well.
Swift is developed in the open at Swift.org, with source code, a bug tracker, forums, and regular development builds available for everyone. This broad community of developers, both inside Apple as well as hundreds of outside contributors, work together to make Swift even more amazing.
