How to parse json in swift 4 an array inside an array - json

Question

I'm having trouble accessing the StatusList array from this API response. How would I get that information?
my current code is and does not work.
let parsedData = try JSONSerialization.jsonObject(with: data!) as! [String:Any]
for list in (parsedData["StatusList"] as? [String])!{
for shipmentstatus in list["Details"]{
//doesn't work
}
}
here is the JSON
{
"MobileAPIError":"",
"StatusList":{
"ErrorMessage":"",
"Details":[
{
"Pro":"000000000",
"BlNumber":"000000",
"ReferenceNumber":"",
"Scac":"CNWY",
"Carrier":"XPO LOGISTICS FREIGHT, INC.",
"ShipperCode":"xx999",
"ShipperName":"W B EQUIPMENT",
"ShipperCity":"WOOD RIDGE",
"ShipperState":"NJ"
},
{
"Pro":"0000000",
"BlNumber":"#00000-R",
"ReferenceNumber":"",
"Scac":"CNWY",
"Carrier":"XPO LOGISTICS FREIGHT, INC.",
"ShipperCode":"xx999",
"ShipperName":"W B EQUIPMENT",
"ShipperCity":"WOOD RIDGE",
"ShipperState":"NJ"
},
]
}
}
EDIT: I would like to try to use JSONDecoder, as it looks like a decent solution.
Would this work?
struct ShipmentStatusList: Decodable {
let MobileAPIError: String
let StatusList: StatusListItems
enum CodingKeys : String, CodingKey {
case MobileAPIError
case StatusList
}
}
struct StatusListItems{
let ErrorMessage: String
let Details: [Details]
}
struct Details {
let Pro: String
let BLNumber: String
let ReferenceNumber: String
}

The value for key StatusList is a dictionary, please note the {}, the array is the value for key Details in statusList
if let parsedData = try JSONSerialization.jsonObject(with: data!) as? [String:Any],
let statusList = parsedData["StatusList"] as? [String:Any],
let details = statusList["Details"] as? [[String:Any]] {
for detail in details {
print(detail["Pro"])
}
}
}
And don't do things like (... as? ...)!, never!
The corresponding Codable structs are
struct Status: Codable {
let mobileAPIError: String
let statusList: StatusList
enum CodingKeys: String, CodingKey { case mobileAPIError = "MobileAPIError", statusList = "StatusList" }
}
struct StatusList: Codable {
let errorMessage: String
let details: [Detail]
enum CodingKeys: String, CodingKey { case errorMessage = "ErrorMessage", details = "Details" }
}
struct Detail: Codable {
let pro, blNumber, referenceNumber, scac: String
let carrier, shipperCode, shipperName, shipperCity: String
let shipperState: String
enum CodingKeys: String, CodingKey {
case pro = "Pro", blNumber = "BlNumber", referenceNumber = "ReferenceNumber"
case scac = "Scac", carrier = "Carrier", shipperCode = "ShipperCode"
case shipperName = "ShipperName", shipperCity = "ShipperCity", shipperState = "ShipperState"
}
}
do {
let result = try JSONDecoder().decode(Status.self, from: data!)
print(result)
} catch { print(error) }
