Swift：如何在字符串表达式中打印出字典键的值？

参见英文答案 > escape dictionary key double quotes when doing println dictionary item in Swift                                    5个
出于某种原因,我只是不能使这个表达式工作：

let expandedBio: Dictionary<String,AnyObject> = ["name":"Saurabh", "profession":"developer", "language":"java", "employed": true]

if let employed : AnyObject = expandedBio["employed"] {
    println("\(expandedBio[\"name\"]) is not available")
}

如何输出println语句？我收到了错误

Unexpected "" character  error in string interpolation

我该怎么做？

在当前版本的Swift中,您必须先将值放在自己的常量/变量中,然后使用它.

if let employed : AnyObject = expandedBio["employed"] {
    let t = expandedBio["name"]
    println("\(t) is not available")
}
