Swift 有文档生成支持吗

Swift是一种开发iOS、macOS、watchOS和tvOS应用程序的现代编程语言。它由苹果公司于2014年推出，成为了iOS应用开发的首选语言之一。与Objective-C相比，Swift具有更简洁、更易读、更安全的语法，同时还提供了许多强大的功能和特性。

swift
var num1 = 10
var num2 = 5
var sum = num1 + num2
var difference = num1 - num2
var product = num1 * num2
var quotient = num1 / num2
print("和：\(sum)")
print("差：\(difference)")
print("积：\(product)")
print("商：\(quotient)")

swift
func gcd(_ a: Int, _ b: Int) -> Int {
    var num1 = a
    var num2 = b
    
    while num2 != 0 {
        let remainder = num1 % num2
        num1 = num2
        num2 = remainder
    }
    
    return num1
}
var result = gcd(24, 36)
print("最大公约数：\(result)")

swift
class Person {
    var name: String
    var age: Int
    
    init(name: String, age: Int) {
        self.name = name
        self.age = age
    }
    
    func sayHello() {
        print("你好，我是\(name)，今年\(age)岁。")
    }
}
var person = Person(name: "张三", age: 20)
person.sayHello()
