Dictionary 如何在Swift中迭代[String:[String]]字典

我有一本字典

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

我将数组分配给第一个键，并且仅分配给第一个键。现在打印参数打印：

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

我如何在这个给定的键上迭代这个数组，以便循环并打印jack、joe和jill

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

使用元组：

let params: [String: [String]] = ["names" : ["jack", "joe", "jill"]]
        for (key, names) in params {
            print("\(key)")
            for name in names {
                print("\(name)")
            }
        }

对于参数{value.forEach{print（$0）}

params[“names”]？.forEach（{print（$0）}）中的（{uu，value）}

let params: [String: [String]] = ["names" : ["jack", "joe", "jill"]]
        for (key, names) in params {
            print("\(key)")
            for name in names {
                print("\(name)")
            }
        }
