here is my code,

struct CoinModel: Identifiable, Codable {
  let id, symbol, name: String
  let image: String
  let currentPrice: Double
  let marketCap, marketCapRank, fullyDilutedValuation: Double?

  let sparklineIn7D: SparklineIn7D?
  let priceChangePercentage24HInCurrency: Double?

  enum CodingKeys: String, CodingKey {
    case id, symbol, name, image
    case currentPrice = "current_price"

    case currentHoldings
   
  }
   
  func updateHoldings(amount: Double) -> CoinModel {

  }

  var currentHoldingsValue: Double {
    return (currentHoldings ?? 0) * currentPrice
  }

  var rank: Int {
    return Int(marketCapRank ?? 0)
  }
   
}

As far as I tried with Xcode 12.5.1, this message was shown on the line case roi:

CodingKey case 'roi' does not match any stored properties

CoinModel.CodingKeys has a case named roi, but there is no stored property roi in CoinModel.

What is it for?
