Answer 1

You can get the currency symbol and code from (NS)Locale with

Swift 1 and 2

let locale = NSLocale.currentLocale()
let currencySymbol = locale.objectForKey(NSLocaleCurrencySymbol)!
let currencyCode = locale.objectForKey(NSLocaleCurrencyCode)!

Swift 3

let locale = Locale.current()
let currencySymbol = locale.object(forKey: .currencySymbol)!
let currencyCode = locale.object(forKey: .currencyCode)!

Swift 3.1+

let locale = Locale.current
let currencySymbol = locale.currencySymbol!
let currencyCode = locale.currencyCode!

This correlates with the user region format settings and works in both iOS and macOS

Answer 2

for swift3

//User region setting return
let locale = Locale.current //NSLocale.current

//Returns true if the locale uses the metric system (Note: Only three countries do not use the metric system: the US, Liberia and Myanmar.)
let isMetric = locale.usesMetricSystem

//Returns the currency code of the locale. For example, for “zh-Hant-HK”, returns “HKD”.  
let currencyCode  = locale.currencyCode

//Returns the currency symbol of the locale. For example, for “zh-Hant-HK”, returns “HK$”.
let currencySymbol = locale.currencySymbol
