how to pass the API parameter and parameter is in array - swift

Question

How to pass array parameter
Parameter
[
{
"id": 0,
"followerId": 1030,
"followingId": 1033,
"followerName": "string",
"followingName": "string",
"createdDate": "string",
"message": "string"
}
] //how to solve this array
API Function
class func postFollowers(params:[String: Any],success:#escaping([FollowingDataProvider]) -> Void, failure:#escaping (String) -> Void){
var request = RequestObject()
request = Services.servicePostForFollower(param: params)
APIManager.Singleton.sharedInstance.callWebServiceWithRequest(rqst: request, withResponse: { (response) in
if (response?.isValid)!
{
//success()
print(response?.object as! JSON)
success(self.followingJSONarser(responseObject: response?.object as! JSON));
//followingJSONarser(responseObject: response?.object as! JSON)
}
else
{
failure((response?.error?.description)!)
}
}, withError: {
(error) in
failure((error?.description)!)
})
}
Parsing
static func followingJSONarser(responseObject:JSON) -> [FollowingDataProvider]{
var dataProvider = [FollowingDataProvider]()
let jsonDataa = responseObject["data"]
print(jsonDataa)
let newJSON = jsonDataa["data"].arrayValue
print(newJSON)
for item in newJSON{
print(item)
dataProvider.append(FollowingDataProvider(id: item["userId"].intValue, followerId: item["userId"].intValue, followingId: item["followingId"].intValue, followerName: item["userName"].stringValue, followingName: item["followingName"].stringValue, createdDate: item["createdDate"].stringValue, message: item["message"].stringValue))
}
return dataProvider
}`

You can try to combine SwiftyJson with Codable
struct Root: Codable {
let id, followerID, followingID: Int
let followerName, followingName, createdDate, message: String
enum CodingKeys: String, CodingKey {
case id
case followerID = "followerId"
case followingID = "followingId"
case followerName, followingName, createdDate, message
}
}
if let con = response?.object as? JSON {
do {
let itemData = try con.rawData()
let res = try JSONDecoder().decode([Root].self, from: itemData)
print(res)
catch {
print(error)
}
}
Also avoid force-unwraps with json
response?.object as! JSON

Following your code you're trying to parse data from API, you can use SwiftyJSON with Alamofire to create an HTTP request (post,get,put,delete,etc)
You should use arrayObject instead of arrayValue
Your code missing the right definition to data parsing
static func followingJSONarser(responseObject:JSON) -> [FollowingDataProvider]{
var dataProvider = [FollowingDataProvider]()
var itemClass = [ItemClass]()
let jsonDataa = responseObject["data"] as! Dictionary
let newJSON = jsonDataa["data"].arrayObject as! Array
Now create a dataModel class to cast data to it
class ItemsClass:NSObject{
var id:Int = 0
var followerId:Int = 0
var followingId:Int = 0
var followerName:String = ""
var followingName:String = ""
var createdDate:String = ""
var message:String = ""
init(data:JSON) {
self.id = data["userId"].intValue
self.followerId = data["userId"].intValue
self.followingId = data["followingId"].intValue
self.followerName = data["userName"].stringValue
self.followingName = data["followingName"].stringValue
self.createdDate = data["createdDate"].stringValue
self.message = data["message"].stringValue
}
}
for item in newJSON{
dataProvider.append(itemClass)
}
return dataProvider
}`
