SK2's Product has localizedPriceString, but some users (including me) might need to calculate other prices, like "cost per month" for their UI. This is my app for example:
I used to calculate that like this on version 3.x:
private extension Purchases.Package {
var pricePerMonth: NSDecimalNumber {
let periodsPerMonth: Int = {
switch self.product.subscriptionPeriod?.unit {
case .day: return 30
case .week: return 4
case .month: return 1
case .year: return 12
default: return 1
}
}() / (self.product.subscriptionPeriod?.numberOfUnits ?? 1)
return self.product.price.dividing(by: NSDecimalNumber(value: periodsPerMonth))
}
var localizedPricePerMonth: String {
let formatter = NumberFormatter()
formatter.numberStyle = .currency
formatter.locale = self.product.priceLocale
return formatter.string(from: self.pricePerMonth)! + " " + Strings.Dates.Unit.perMonth
}
}Luckily the locale is part of the jsonRepresentation of an SK2 Product.
