I am attempting to parse the following json data:

Below is my struct:

struct Sourcet: Decodable

let response = try JSONDecoder().decode(Album.self, from: data)

I continue getting the error:

intValue: nil) ("_source").", underlyingError: nil))

Is this due to the json information being an array?.How would I be able to parse this information?

Your struct Album is wrong and you're parsing Album.self single object instead of array.

Try below code :

struct Album: Decodable 
 var source: Sourcet // change array to single object
 enum CodingKeys: String, CodingKey 
 case source = "_source"
 


struct Sourcet: Decodable 
 var nome, uf : String

To parse json in model :

do 
 let response = try JSONDecoder().decode([Album].self, from: data)
 for item in response 
 print(item.source.nome)
 
 catch
 print("Error: ",error)
