在数组中插入一个对象 swift

Question

我从 API 响应中得到一个对象，如下所示。

"Home":[
{
"type":"Something",
"id":"Something",
"interval":3,
"category":"Something",
"title":"Something",
"vc":[]
},
{
"type":"Something",
"id":"Something",
"TableFooterDisclaimer":"",
"category":"Something",
"title":"Something",
"vc":[
{
"Something":"Something",
"id":0,
"Something":"Something",
"Something":"Something",
"Something":"Something",
"Something":"Something",
"Something":"Something",
},
{
"Something":"Something",
"id":1,
"Something":"Something",
"Something":"Something",
"Something":"Something",
"Something":"Something",
"Something":"Something",
},
{
"Something":"Something",
"id":2,
"Something":"Something",
"Something":"Something",
"Something":"Something",
"Something":"Something",
"Something":"Something",
}
]
},

我正在尝试再插入一条如下所示的记录。

let object : [String : Any] = [
"Something":"Something",
"id":1,
"Something":"Something",
"Something":"Something",
"Something":"Something",
"Something":"Something",
"Something":"Something",
]

这个object 我试图插入Home 的第一个索引的vc 数组中，如下所示，但遇到问题。

if let serverArray = info["Home"] as? [[String: AnyObject]] {
     self.myArray = serverArray
     self.myArray![1]["vc"]?.insert(self.object, at: 0)
}

我尝试将 let object : [String:Any] 转换为 [String:AnyObject] 但这也没有用。

你可以试试这样的：

if var serverArray = info["Home"] as? [[String: Any]] {
    if serverArray.count > 1 {
        var vcs = serverArray[1]["vc"] as? [[String: Any]]
        vcs?.insert(self.object, at: 0)
        serverArray[1]["vc"] = vcs
    }
    self.myArray = serverArray
}

但它有点丑。

使用@JoakimDanielson 评论的Codable and JSONDecoder 会更好。
