CurrencyConverter (Swift 5.0)

A simple currency converter written in Swift 5.
The exchange rates are fetched from the following XML file: https://www.ecb.europa.eu/stats/eurofxref/eurofxref-daily.xml
This Currency Converter is used in the Objective Calculator app. Check it out: http://itunes.apple.com/app/id1287000522

How to use:
• Add the "CurrencyConverter.swift" file to your project
• Create a CurrencyConverter instance
• Call the updateExchangeRates method
• After it updates the exchange rates, call the convert method
• That's it!

Example

class ViewController: UIViewController {

    // Creates the Currency Converter instance:
    let currencyConverter = CurrencyConverter()
    
    override func viewDidLoad() {
        super.viewDidLoad()
        
        // Updates the exchange rates:
        currencyConverter.updateExchangeRates(completion: {
            // The code inside here runs after all the data is fetched.
            
            // Now you can convert any currency:
            // • Example_1 (USD to EUR):
            let doubleResult = self.currencyConverter.convert(10, valueCurrency: .USD, outputCurrency: .EUR)
            print("••• 10 USD = \(doubleResult!) EUR •••")
            
            // • Example_2 (EUR to GBP) - Returning a formatted String:
            let formattedResult = self.currencyConverter.convertAndFormat(10, valueCurrency: .EUR, outputCurrency: .GBP, numberStyle: .decimal, decimalPlaces: 4)
            print("••• Formatted Result (10 EUR to GBP): \(formattedResult!) •••")
        })
    }

}
