How to show the price of an SKProduct

Swift version: 5.4

StoreKit products come with price and priceLocale properties 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)!
    }
}
