Persist Data

For persistent data like display and currency code the @AppStorage property wrapper was used.

@AppStorage("selectedCurrencyBase") var selectedCurrencyCode: String = "EUR"
@AppStorage("isDarkModeEnabled") var isDarkModeEnabled = false

API Reference

For the implementation of the Currencies application, I utilized the ExchangeRate-API, which allows you to retrieve current currency exchange rates, perform currency conversions and fetch historical exchange rate data.

Parameter	Type	Value	Description
api_key	string	b1b71f168dab8cfbff14f4d3	Required
currency_base	string	EUR	Required

  GET https://v6.exchangerate-api.com/v6/b1b71f168dab8cfbff14f4d3/latest/EUR

This will return (with JSON format) the exchange rates from your base code to all the other currencies which supported:
