ios - 我在哪里可以找到 Swift 的 "math, strings, etc... libraries"？

Question

我正在查看 Swift 文档，但找不到其他语言的引用资料...

示例:sin()、cos()、abs() 用于数学，uppercase() , lowercase() 用于字符串，sort(), pop(), push() 用于数组等。 ..

对于字符串，我找到了这个 in the docs :

Swift’s String type is bridged seamlessly to Foundation’s NSString class. If you are working with the Foundation framework in Cocoa or Cocoa Touch, the entire NSString API is available to call on any String value you create, in addition to the String features described in this chapter. You can also use a String value with any API that requires an NSString instance.

你能指点我一些文档或者我在哪里可以找到列出的那些函数吗？

Answer 1

看起来这是可行的...

import Foundation
var theCosOfZero: Double = Double(cos(0))  // theCosOfZero equals 1
