Get currency symbols from currency code with swift

Question

How can I get the currency symbols for the corresponding currency code with Swift (macOS).

Example:

• EUR = €1.00
• USD = $1.00<

Answer 1

The proper way to do this is to let the frameworks provide the information for you.

You can retrieve that information using an obscure class method on NSLocale called localeIdentifierFromComponents(). That method will take a dictionary that defines various attributes of your locale, and then returns an identifier you can use to actually construct an NSLocale instance. Once you have the NSLocale, you can ask it for its CurrencySymbol, like this:

let currencyCode = "CAD"

let localeComponents = [NSLocaleCurrencyCode: currencyCode]
let localeIdentifier = NSLocale.localeIdentifierFromComponents(localeComponents)
let locale = NSLocale(localeIdentifier: localeIdentifier)
let currencySymbol = locale.objectForKey(NSLocaleCurrencySymbol) as! String
// currencySymbol is "CA$"
