Swift How to remove optional String word

Question

How do I remove Optional word

public func getCurrencySymbolFromCurrencyCode(currencyCode: String) -> String {
    // let currencyCode: String = "EUR"
    let locale: NSLocale = NSLocale(localeIdentifier: currencyCode)
    let currencySymbol: String = "\(locale.displayNameForKey(NSLocaleCurrencySymbol, value: currencyCode))"
    print("Currency Symbol : \(currencySymbol)")

    return currencySymbol
}

Above code produces as follow:

Optional("$")

My question is why there is Optional("$") there, how can I remove the optional and just printing $

//replace your code with this your are not force unwrapping the symbol

      public func getCurrencySymbolFromCurrencyCode(currencyCode: String) -> String! {
          // let currencyCode: String = "EUR"
          let locale: NSLocale = NSLocale(localeIdentifier: currencyCode)
          let symbol = locale.displayNameForKey(NSLocaleCurrencySymbol, value: currencyCode)!
          let currencySymbol: String = "\(symbol)"
          print("Currency Symbol : \(currencySymbol)")

          return currencySymbol
      }
