so I'm trying to request an api with json decoder using a decodable struct, the problem is that one of the json's property returned starts with a number like "24h_change" : "12323", the question is how to convert that property into a variable, here's my code:
struct CoinModel : Decodable {
let 24h_volume_usd : String? // here's the problem
let id : String?
let name : String?
let symbol :String?
let rank: String?
let price_usd: String?
}
the api returns
[{
"id": "bitcoin",
"name": "Bitcoin",
"symbol": "BTC",
"rank": "1",
"price_usd": "8660.0",
"24h_volume_usd": "1231213"
}]
ViewController
URLSession.shared.dataTask(with: apiUrl) { (data, Reponse, err) in
if err != nil{
print("error getting JSON")
}
guard let data = data else{return}
do{
let JSON = try JSONDecoder().decode([CoinModel].self, from: data)
self.coinArray = JSON
}catch let err {
print (err)
}
}.resume()
