ios - 在swift 4中创建一个包含数组和字典的字典

Question

我只想创建一个 API JSON 结构。以下是帖子正文键和对象。在 Swift 4 中是否有类似于 Objective C 的带有键和值的对象的方法？

{
    "name": "switch 1",
    "type": "Switch",
    "gatewayId":515,
    "serialKey": "98:07:2D:48:D3:56",
    "noOfGangs": 4,
    "equipments": [
        {
            "name": "light",
            "type": "Light",
            "port": "1"
        },
        {
            "name": "television",
            "type": "Television",
            "port": "3"
        }
    ]
}

您可以通过注释类型并用方括号替换大括号来按字面意义创建字典

let dict : [String:Any] = ["name": "switch 1", "type": "Switch", "gatewayId":515, "serialKey": "98:07:2D:48:D3:56", "noOfGangs": 4, "equipments": [[ "name": "light", "type": "Light", "port": "1" ], ["name": "television", "type": "Television", "port": "3" ]]]

或者构建它:

var dict : [String:Any] = ["name": "switch 1", "type": "Switch", "gatewayId":515, "serialKey": "98:07:2D:48:D3:56", "noOfGangs": 4]
var equipments = [[String:String]]()
equipments.append(["name": "light", "type": "Light", "port": "1" ])
equipments.append(["name": "television", "type": "Television", "port": "3" ])
dict["equipments"] = equipments
