Localized currency symbol from NumberFormatter

Question

how to set NumberFormatter to return currency symbol not the iso one but local which is visible in iOS locale settings pane. Like for Polish currency I need to have “zł” symbol not the “PLN”.

I cannot find any way to get it from system as this cannot be hardcoded. IAP localized price also uses “zł” not “PLN”

I tried this way:

let formatter = NumberFormatter()
formatter.numberStyle = .currency
formatter.currencySymbol = Locale.current.currencySymbol
formatter.maximumFractionDigits = 2

let price = formatter.string(from: (offeringPrice / 12) as NSNumber) ?? ""

but whatever I try to use as currency symbol I always get in return "PLN"

`Locale` can have 2 components, the language and the region. The `currencySymbol` can vary depending on the region and language independently. If I don't set the region, but just the language: `Locale(identifier: "pl").currencySymbol` it returns `"¤"`, but if I set both the region and language: `Locale(identifier: "pl-PL").currencySymbol` It returns `"zł"`. I'm wondering if you are getting unexpected results due to the region not being set correctly on your test device. — Ryan Maloney, May 28 '20 at 18:50
I have locale Poland and region Poland set in device, localised IAP price returns "zł" so this is bit weird — Paweł Madej, May 28 '20 at 18:57
my app language is English only for now. maybe this is cause? and locale en_PL for whatever reason ;/ — Paweł Madej, May 28 '20 at 19:00

If you set formatter.locale to pl_PL it works:

let formatter = NumberFormatter()
formatter.numberStyle = .currency
formatter.maximumFractionDigits = 2
formatter.currencyCode = "PLN"

let polandLocale = Locale(identifier: "pl_PL")
let usLocale = Locale(identifier: "en_US")

let offeringPrice = 50.0
let price = (offeringPrice / 12) as NSNumber

formatter.locale = usLocale
formatter.string(from: price) // "PLN 4.17"

formatter.locale = polandLocale
formatter.string(from: price) // "4,17 zł"

I've found this solution

    func getCurrencySymbol(from currencyCode: String) -> String? {
        let locale = NSLocale(localeIdentifier: currencyCode)
        if locale.displayName(forKey: .currencySymbol, value: currencyCode) == currencyCode {
            let newlocale = NSLocale(localeIdentifier: currencyCode.dropLast() + "_en")
            return newlocale.displayName(forKey: .currencySymbol, value: currencyCode)
        }
        return locale.displayName(forKey: .currencySymbol, value: currencyCode)
    }
