Rates array or catalog

[dasoga]

What do you think send the rates as array, or maybe send a catalog of rates to make it dynamically, because now I'm building an iOS client, but I had to create an enum for rates, if you add other rate then I'll have to update the client app.

Thanks in advance for your comments.

@dasoga The European Central Bank produces the dataset. They do occasionally add or remove currencies; unfortunately I would not be able to anticipate such changes.

I mean

Instead of this.

{
    "base": "USD",
    "date": "2018-01-09",
    "rates": {
        "AUD": 1.2774,
        "BGN": 1.6391,
        "BRL": 3.2326,
        "CAD": 1.2425,
        "CHF": 0.98282,
        "CNY": 6.5257,

        "HRK": 6.2416,

Could be better if you return an array of rates.

{
    "base": "USD",
    "date": "2018-01-09",
    "rates": [
        "AUD": 1.2774,
        "BGN": 1.6391,
        "BRL": 3.2326,
        "CAD": 1.2425,
        "CHF": 0.98282,
        "CNY": 6.5257,
        "CZK": 21.4,
        "DKK": 6.2411,
        "GBP": 0.73978,
        "HKD": 7.8212,
        "HRK": 6.2416,
        "HUF": 259.27,
        "IDR": 13442,
        "ILS": 3.4442,
        "INR": 63.713,
        "JPY": 112.56,
        "KRW": 1068.4,
        "MXN": 19.218,
        "MYR": 4.0095,
        "NOK": 8.1055,
        "NZD": 1.3913,
        "PHP": 50.28,
        "PLN": 3.5028,
        "RON": 3.8996,
        "RUB": 57.035,
        "SEK": 8.2373,
        "SGD": 1.3352,
        "THB": 32.25,
        "TRY": 3.7582,
        "ZAR": 12.348,
        "EUR": 0.83808
    ]
}
