Question

我在Swift中创建了以下代码。当我运行它时，我会得到类似的东西：

今天是（枚举价值）周一和周三的班级是CIS 110

我想得到的是当天的名字（例如，＆＃34;星期一和＃34;）。当我在调试模式下运行代码并观察变量时，＆＃34;工作日＆＃34;，我看到了星期几。但是，当代码完成运行时，我最终会得到＆＃34;（枚举值）＆＃34;。

代码：

import Foundation
import Darwin


//weekdays
enum Weekdays: Int{
    case Monday = 1, Tuesday, Wednesday, Thursday, Friday, Saturday, Sunday
}

//get random day of the week
func getDay() ->Int{
    let day = Int(1 + arc4random_uniform(7)) //random number 1 - 7
    return day
}


//determine schedule
var schedule: String = ""

func getSchedule(day: Int) -> String {
    switch day{
    case 1, 3:
        schedule = "Monday and Wednesday's class is CIS 110"
    case 2, 4:
        schedule = "Tuesday and Thursday's classes are ENG 111 and PSY 150"
    default:
        schedule = "It's the weekend! Have fun!"
    }
    return schedule
}
let day = getDay()
//take that random day and use the number the rawValue of the 
//Weekdays to get the weekday
let weekday = Weekdays(rawValue: day)!

println("Today is \(weekday)")
println(getSchedule(day))

采用Printable（在Swift 2.0中称为CustomStringConvertible）并实现description覆盖，以实现您的目标。

如何将从枚举中接收的值转换为Swift中的String？
