First issue I addressed
I am working on an APIService using Alamofire, I tried to print the response
and the I got the data successfully, but unfortunately the data from JSON turns to nil when I parse it to the attendees
Object. How can I reflect the data from json to the attendees object?
Second Issue
I solved the 1st issue, after all the debugging I had. The codes I used was written in my answer below. I parsed data from JSON going to attendees
but as I checked only the first array was fetch. How can I get all the data inside the JSON? Hope you can help me. Thank you.
func getParticipants(passcode: String,
participantType: ParticipantType,
successBlock: @escaping (Attendees?) -> Void,
failureBlock: @escaping (Error) -> Void)
{
let attendeesURL = URL(string: "\(GET_PARTICIPANTS_URL)/\(passcode)/\(participantType)")
Alamofire.request(attendeesURL!, method: .get).responseJSON { (response) in
print(response)
if let error = response.error
{
failureBlock(error)
return
}
if let attendeeJSON = response.result.value as? [Dictionary<String, Any>],
let attendeeObj = attendeeJSON.first {
print(attendeeObj)
let attendees = Attendees.init(JSON: attendeeObj)
successBlock(attendees)
}
}
}
}
JSON

I solved my own issue. :D
Alamofire.request(attendeesURL!, method: .get).responseJSON { (response) in
print(response)
if let error = response.error
{
failureBlock(error)
return
}
if let jsonDictionary = response.result.value as? [Dictionary<String, Any>]{
if let eventparticipants = jsonDictionary.first {
print(eventparticipants)
if let partObj = eventparticipants["event_participants"] as? [[String : Any]]{
let attendeeObj = partObj.first
let attendees = Attendees.init(JSON: attendeeObj!)
successBlock(attendees)
}
}
}
}
Instead of using first
which gets only the first item of the sequence use a loop respectively.
if let events = response.result.value as? [[String : Any]] {
for event in events {
if let eventparticipants = event["event_participants"] as? [[String : Any]] {
print(eventparticipants)
for participant in eventparticipants {
let attendees = Attendees.init(JSON: participant)
successBlock(attendees)
}
}
}
}
I recommend to decode the JSON directly into structs with Decodable
