Add this line to your Cartfile:

4. Implement BundleReceiptRequestDelegate to retrieve Receipt:

   func bundleReceiptRequest(bundleReceiptRequest: BundleReceiptRequest, didRetrieveReceipt receipt: Receipt?) {
   
       guard let receipt = receipt where receipt.status == 0 else {
           handleMissingReceipt()
       }
   
       if let purchaseDate = receipt?.purchaseDate {
           processApplicationPurchaseDate(purchaseDate)
       }
   
   }
