Just a tiny app that fetches currency exchange rates
Dollar just fetches the current currency exchange rate between USD and CAD, and periodically fetches the exchange rate in the background and sends notifications when the exchange rate differs by 0.003 of the last fetched rate. There's also a Today Extension that shows the live exchange rate too.
Wanted to monitor the currency exchange for USD and CAD easily with minimal network traffic
Just go into CurrencyManager.swift and modify the request url:
// Change the USD_CAD to your desired exchange symbol
private static let requestUrl = URL(string: "https://free.currencyconverterapi.com/api/v5/convert?q=USD_CAD&compact=y")!Then, go to CurrencyResponse.swift and do something similar. In CurrentResponse.CodingKeys, change the rawValue of exchange to the same exchange symbol from the CurrencyManager file.
enum CodingKeys: String, CodingKey {
case exchange = "USD_CAD" // change this
