Assuming you know the productID
:
First
import StoreKit
Then in your code
let productID: Set = ["premium"]
let request = SKProductsRequest(productIdentifiers: productID)
request.delegate = self
request.start()
and in the SKProductsRequestDelegate
:
func productsRequest(request: SKProductsRequest, didReceiveResponse response: SKProductsResponse) {
if response.products.count > 0 {
let product = response.products[0]
let payment = SKPayment(product: product)
SKPaymentQueue.defaultQueue().addPayment(payment)
}
}
