How to show the price of an SKProduct
StoreKit products come with price and priceLocale property, but it takes a little effort to combine those two together in order to show a user-friendly price in your interface.
Fortunately, one small extension to SKProduct will provide you with a localizedPrice property you can use to do that work for you:
extension SKProduct {
var localizedPrice: String {
let formatter = NumberFormatter()
formatter.numberStyle = .currency
formatter.locale = priceLocale
return formatter.string(from: price)!
}
