如何在Swift中遍历[String:[String]]字典 [英] How do I iterate through a [String:[String]] Dictionary in Swift

问题描述

我有字典.

var params: [String: [String]] = [:]

我仅将数组分配给第一个键和第一个键.现在打印参数打印:

I assign an array to the first key and the first key only. Now print params prints :

["names" : ["jack", "joe", "jill"]]

如何在给定的键处迭代此数组，以便可以遍历并打印杰克，乔和吉尔?

How do I iterate through this array at this given key so that I could loop through and print jack, joe, and jill?

推荐答案

for (key, names) in params {
    for name in names {
        print("\(name))
    }
}
