+# 关于 Swift
 
-# About Swift
+理解该语言的高级目标。
 
-Understand the high-level goals of the language.
+Swift 是编写手机、平板电脑、台式机、服务器或任何运行代码的设备的绝佳方式。
+它是一种安全且快速的编程语言，结合了现代语言思想的精华，并汲取了来自多元化的开源社区的智慧。
 
-Swift is a fantastic way to write software
-for phones, tablets, desktops, servers,
-or anything else that runs code.
-It's a safe and fast programming language
-that combines the best in modern language thinking
-with wisdom from a diverse open source community.
+Swift 对于初学者来说很友好，同时也没有牺牲经验丰富的程序员所需要的强大和灵活性。
+它是一种工业级的编程语言，但又有着脚本语言般的表达力和可玩性。
+编译器经过精心优化，可以提供卓越的性能表现。同时语言本身也经过精心设计，以便于开发使用。
+两者都没有做出任何妥协，鱼与熊掌兼得。
 
-Swift is friendly to new programmers,
-without sacrificing the power and flexibility
-that experienced programmers need.
-It's an industrial-quality programming language
-that's as expressive and enjoyable as a scripting language.
-The compiler is optimized for performance
-and the language is optimized for development,
-without compromising on either.
+Swift 通过采用现代编程模式来避免大量常见编程错误：
 
-Swift defines away large classes of common programming errors
-by adopting modern programming patterns:
+- 变量始终在使用前被初始化。
+- 数组索引会进行越界检查。
+- 整数运算会进行溢出检查。
+- 可选类型确保 `nil` 值能够得到明确处理。
+- 内存被自动管理。
+- 错误处理允许从意外失败中进行有控制的恢复。
 
-- 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 代码经过编译和优化，可以充分发挥现代硬件的性能。
+语法和标准库的设计都遵循一个指导原则，
+即编写代码的最直观方式也应该是性能最高效的方式。
+安全性和速度的结合使得 Swift 成为从 “Hello，world！” 到整个操作系统的绝佳选择。
 
-Swift code is compiled and optimized to get the most out of modern hardware.
-The syntax and standard library have been designed
-based on the guiding principle that
-the obvious way to write your code should also perform the best.
-Its combination of safety and speed make Swift an excellent choice for
-everything from "Hello, world!" to an entire operating system.
+Swift 融合了对于来自其他流行语言的开发者来说很熟悉的现代且轻量的语法，
+同时还拥有类型推断和模式匹配等强大功能，
+使得复杂的概念能够以简洁明了的方式表达出来。
+因此，代码更易于阅读、编写和维护。
 
-Swift combines a modern, lightweight syntax
-that's familiar for developers coming from other popular languages
-with powerful features like type inference and pattern matching,
-allowing complex ideas to be expressed in a clear and concise manner.
-As a result, code is easier to read, write, and maintain.
-
-Swift continues to evolve with thoughtful new features and powerful capabilities.
-The goals for Swift are ambitious.
-We can’t wait to see what you create with it.
