read JSON result as array of dictionary - json

Question

how to parse following JSON result
{
"AddedByName": "jhon",
"ApproveAction": 0,
"ApproveActionName": "",
"photos": null,
"Status": 0,
},
{
"AddedByName": "mike",
"ApproveAction": 0,
"ApproveActionName": "",
"photos": null,
"Status": 0,
},
{
"AddedByName": "someone",
"ApproveAction": 0,
"ApproveActionName": "",
"photos": [
{
"Id": 53,
"Serial": 1,
"Url": "0afe88a3-76e1-4bac-a392-173040936300.jpg"
}
],
"Status": 0,
}
how can i reach the "photos" array ?
I already declare local array of dictionary to hold the whole responses as following
var myLocalArray = [[String:Any]]()
and fill it from the JSON response like this
if let Json = response.result.value as? [String:Any] {
if let ActionData = Json["ActionData"] as? [[String:Any]] {
self. myLocalArray = ActionData
}
}
and it works
but i couldn't reach the "photos" array please help

Answer 1

I will give you smart solution than can be useful at each you try to transform you Json to useful data model and make it easier to manipulate .
Using the power of Decodable .
This Model will help you to capture you Json
struct User: Decodable {
var AddedByName: String
var ApproveAction: Int
var ApproveActionName: String
var photos: [Photo]?
var Status: Int
struct Photo: Decodable {
var Id: Int
var Serial: Int
var Url: String
}
}
And now will be just one line to get your Json to structure data:
let responseData = try JSONDecoder().decode([User].self, from: jsonD)

#swiftIos provided the answer with Decodable which is absolutely a better way to handle the situation.
But with your current you can access the photos from self.myLocalArray:
if let jsonData = response.result.value as? [String: Any] {
if let actionData = jsonData["ActionData"] as? [[String:Any]] {
self.myLocalArray = actionData
}
}
Now you have array for actionData, so access the photos by extracting the actionData for particular index as self.myLocalArray[0]. In whole:
let index = 0
if self.myLocalArray.count > index {
if let photoArrayIndex0 = self.myLocalArray[index]["photos"] as? [[String: Any]] {
print(photoArrayIndex0)
}
}
