How to map Nested Array of Objects using Swift Object Mapper? - json

Question

I am trying to map an array of objects using Object Mapper
I have this code so far, and my mapping is not successful
do {
if let data = data, let sectorData = Mapper<SubSectorsModel>().mapArrayOfArrays(JSONObject: try JSONSerialization.data(withJSONObject: data, options: [])) {
completionHandler(sectorData,(response as! HTTPURLResponse), error)
print("SectionData Received Successfully")
}
} catch {
completionHandler(nil,(response as! HTTPURLResponse), error)
print("Error parsing json get sector data: ", error.localizedDescription)
}
My Json data is as follows:
[

If you just want to send completionHandler anyway, use code below:
struct MyJsonStruct : Decodable {
struct SectorStruct : Decodable {
var ID : String
var NAME : String
}
var SECTOR_NAME : String
var ID : String
var SECTOR : [SectorStruct]
}
func handle(_ data : Data ) {
do {
let sectorData = try JSONDecoder().decode(MyJsonStruct.self, from: data) as MyJsonStruct
let yourArray = sectorData.SECTOR // if you need an array result
completionHandler(sectorData,(response as! HTTPURLResponse), error)
print("SectionData Received Successfully")
} catch {
completionHandler(nil,(response as! HTTPURLResponse), error)
print("Error parsing json get sector data: ", error.localizedDescription)
}
}
