How to get Local Currency for SKProduct | Display IAP Price in Swift

RileyDev picture RileyDev · Apr 22, 2016 · Viewed 13.5k times · Source

I am trying to display the price of an in app purchase using the local currency, so the correct dollar is displayed for both US & CA as well as Euro, GBP etc.

I know each SKProduct has a price which appears during the transaction as an alert view, this appears when confirming the purchase.

However I want to display the price before confirmation.

I was thinking to do something like this:

//Products Array
var productsArray: Array<SKProduct!> = []

//Request Products
    func productsRequest(request: SKProductsRequest, didReceiveResponse response: SKProductsResponse) {
        if response.products.count != 0 {
            for product in response.products {
                print("\(product.localizedTitle)")
                productsArray.append(product)
            }
        }
        else {
            print("There are no products.")
        }

        if response.invalidProductIdentifiers.count != 0 {
            print("\(response.invalidProductIdentifiers.description)")
        }            
     }


let item = SKProduct
  for i in productsArray {
    if i.localizedTitle == "com.Company.App.item1" 
      item = i
    }
  }

But this doesn't work as i Doesn't seem to have a price property.

Does anybody know how I can set a label text to the price of an iAP using the correct local currency?

For example £1.49 GBP is $1.99 US dollars using Apples Pricing Matrix and outputting the value should match the values of the product price when confirming the transaction.

Swift 5 and 2019 version:

Create an extension to SKProduct so you can access product.localizedPrice conveniently:

extension SKProduct {
    fileprivate static var formatter: NumberFormatter {
        let formatter = NumberFormatter()
        formatter.numberStyle = .currency
        return formatter
    }

    var localizedPrice: String {
        if self.price == 0.00 {
            return "Get"
        } else {
            let formatter = SKProduct.formatter
            formatter.locale = self.priceLocale

            guard let formattedPrice = formatter.string(from: self.price) else {
                return "Unknown Price"
            }

            return formattedPrice
        }
    }
}

Original Anser:

Swift 4.2 version of Olivier's answer

func priceStringForProduct(item: SKProduct) -> String? {
    let price = item.price
    if price == NSDecimalNumber(decimal: 0.00) {
        return "GET" //or whatever you like really... maybe 'Free'
    } else {
        let numberFormatter = NumberFormatter()
        let locale = item.priceLocale
        numberFormatter.numberStyle = .currency
        numberFormatter.locale = locale
        return numberFormatter.string(from: price)
    }
}
