I need help getting all the JSON data API provides - arrays

Question

Hello can you help me get array of all the data including global_rank, brawlhalla_id, etc.? I am only able to get array of legend like legend_id, legend_key_name. This is the json
{
"name": "bmg | dan",
"brawlhalla_id": 2,
"rating": 1745,
"peak_rating": 1792,
"tier": "Platinum 2",
"wins": 207,
"games": 391,
"region": "US-E",
"global_rank": 5698,
"region_rank": 1644,
"legends": [
{
"legend_id": 4,
"legend_name_key": "cassidy",
"rating": 1736,
"peak_rating": 1792,
"tier": "Platinum 1",
"wins": 161,
"games": 300
},
{
"legend_id": 21,
"legend_name_key": "barraza",
"rating": 1640,
"peak_rating": 1640,
"tier": "Gold 5",
"wins": 41,
"games": 77
}
],
...
My code looks like this:
import SwiftUI
class BrawlhallaSevice {
let url = URL(string: "http://sion.red/brawlhalla/ranked.json")!
func getBrawlhalla(completion: #escaping (Result<[Brawlhalla], Error>) -> Void) {
URLSession.shared.dataTask(with: url) { data, response, error in
guard error == nil else {
completion(.failure(error!))
return
}
completion(.success(self.getBrawlhallaResponse(fromData: data!)))
}.resume()
}
private func getBrawlhallaResponse(fromData data: Data) -> [Brawlhalla] {
let brawlhallaData = try? JSONDecoder().decode(BrawlhallaResponse.self, from: data)
if let brawlhallaD = brawlhallaData {
print(brawlhallaD)
//return brawlhallaD.legends works and returns array of data about a legend
return brawlhallaD
}
return [Brawlhalla(legend_name_key: "Error", rating: 0, peak_rating: 0, tier: "Error")]
}
}
But it throws an error: "Cannot convert return expression of type 'BrawlhallaResponse' to return type '[Brawlhalla]'".
This is how my models look
import Foundation
struct BrawlhallaResponse: Codable {
let legends: [Brawlhalla]
let name: String
let rating: Int
let peak_rating: Int
let tier: String
}
import Foundation
struct Brawlhalla: Codable {
let name: String
let rating: Int
let peak_rating: Int
let tier: String
}
I have tried many changes to the code but nothing seem to work.

I think you got the right code, but it seems like you're trying to return brawhallaD in that if let statement. You're getting the error because your return type is [Brawlhalla], but you're returning a decodedResponse of type BrawlhallaResponse.
So what you can do is this:
class BrawlhallaSevice {
let url = URL(string: "http://sion.red/brawlhalla/ranked.json")!
func getBrawlhalla(completion: #escaping (Result<BrawlhallaResponse?, Error>) -> Void) {
URLSession.shared.dataTask(with: url) { data, response, error in
guard error == nil else {
completion(.failure(error!))
return
}
guard let safeData = data else { return }
completion(.success(self.getBrawlhallaResponse(fromData: safeData)))
}.resume()
}
private func getBrawlhallaResponse(fromData data: Data) -> BrawlhallaResponse?{
let brawlhallaData = try? JSONDecoder().decode(BrawlhallaResponse.self, from: data)
if let brawlhallaD = brawlhallaData {
return brawlhallaD // Will return BrawlhallaResponse.peak_rating and also legends
}
return nil
}
}
