A lightweight wrapper for Apple’s StoreKit, written in Swift.
StoreKitCompanion is available on SPM. Just add the following to your Package file:
import PackageDescription
let package = Package(
dependencies: [
.Package(url: "https://github.com/recisio/StoreKitCompanion.git", majorVersion: 1)
]
)
Add StoreKitCompanion.swift
to your project.
StoreKitCompanion lets you fetch products, launch payment transactions and send App Store Receipt data over the network for validation in a couple of lines of code.
Fetching products is easy, call fetchProductsWithIdentifiers(_:completion:)
and pass in a set of product identifiers. At a very minimum, also supply a completion closure to get the valid SKProduct
objects returned. Optionally, supply a failure closure to handle errors.
StoreKitCompanion.sharedInstance.fetchProductsWithIdentifiers(["com.mycompany.MyKillerProduct"], completion: { products, invalids in
print("Got products", products)
print("Got invalids", invalids)
})
Before trying to buy something, you should check whether users are allowed to make payments. You can do so by calling canMakePayments()
.
StoreKitCompanion.sharedInstance.canMakePayments()
Payments are submitted to the default payment queue (SKPaymentQueue.defaultQueue()
) and StoreKitCompanion observes it. Whenever something happen on it, StoreKitCompanion sends notifications, and calls closures that you set.
// Provide a closure to be called when transactions are updated
StoreKitCompanion.sharedInstance.transactionsUpdateHandler = { queue, transactions in
// Process transactions..
}
// Add a payment, quantity is 1 by default
StoreKitCompanion.sharedInstance.addPaymentForProductIdentifier("com.mycompany.MyKillerProduct")
You can restore completed transactions by calling restoreCompletedTransactionsWithUsername(_:)
.
You may also provide an optional username.
Callbacks that you set are called in response to the restoration request.
StoreKitCompanion.restoreCompletedTransactionsWithUsername()
Details about App Store receipt validation can be found on Apple’s website. While StoreKitCompanion doesn’t perform any local validation (yet?) of the receipt, it let’s you send it to a server for validation.
By default, StoreKitCompanion will send the data using a HTTP POST request, with a parameter named receiptData
, but you can override those settings if you need to.
// First supply a validation URL, StoreKitCompanion will use it
StoreKitCompanion.sharedInstance.validationURLString = "http://myserver.com"
// Send the data out
StoreKitCompanion.sharedInstance.sendReceiptWithPOSTRequest() { responseData, error in
print("Got response", responseData)
print("Got error", error)
}
To customize the way the receipt is sent, use sendReceiptWithDescriptor(_:completion:)
and provide it with any object that adopts the ReceiptValidationRequestDescriptor
protocol. Default values are already provided in a protocol extension, so override only what’s needed.
struct MyRequestDescriptor: ReceiptValidationRequestDescriptor {
// Name parameters differently or add parameters
func parametersWithReceiptData(receiptData: NSData) -> [String: AnyObject]? {
return ["best_param_name": receiptData, "new_param": "new_param_value"]
}
}
// Send the data out
StoreKitCompanion.sharedInstance.sendReceiptWithDescriptor(MyRequestDescriptor()) { responseData, error in
print("Got response", responseData)
print("Got error", error)
}
StoreKitCompanion watches the default payment queue and sends notifications :
/**
The name of the notification sent when the payment queue finished to restore completed transactions.
User info dictionary contains a reference to the `SKPaymentQueue` object.
*/
public static let PaymentQueueDidFinishRestoringCompletedTransactions = "SKCPaymentQueueDidFinishRestoringCompletedTransactions"
/**
The name of the notification sent when transactions are updated.
User info dictionary contains a reference to the `SKPaymentQueue` object and an array of `SKPaymentTransaction` objects.
*/
public static let PaymentQueueDidUpdateTransactions = "SKCPaymentQueueDidUpdateTransactions"
/**
The name of the notification sent when transactions are removed.
User info dictionary contains a reference to the `SKPaymentQueue` object and an array of `SKPaymentTransaction` objects.
*/
public static let PaymentQueueDidRemoveTransactions = "SKCPaymentQueueDidRemoveTransactions"
/**
The name of the notification sent when downloads are updated
User info dictionary contains a reference to the `SKPaymentQueue` object and an array of `SKDownload` objects.
*/
public static let PaymentQueueDidUpdateDownloads = "SKCPaymentQueueDidUpdateDownloads"
/**
The name of the notification sent when the payment queue fails to restore completed transactions.
User info dictionary contains a reference to the `SKPaymentQueue` object and a reference to the `NSError` object.
*/
public static let PaymentQueueDidFailRestoringCompletedTransactions = "SKCPaymentQueueDidFailRestoringCompletedTransactions"
Another way to handle payment queue events is to provide StoreKitCompanion with closures for those events :
public typealias CompletedTransactionsRestoreCompletion = (SKPaymentQueue) -> Void
public typealias CompletedTransactionsRestoreFailure = (SKPaymentQueue, NSError) -> Void
public typealias DownloadsUpdateCompletion = (SKPaymentQueue, [SKDownload]) -> Void
public typealias TransactionsUpdateCompletion = (SKPaymentQueue, [SKPaymentTransaction]) -> Void
public typealias TransactionsRemovalCompletion = (SKPaymentQueue, [SKPaymentTransaction]) -> Void
// ....
/**
Handles successful completed transactions restoration
*/
public var completedTransactionsRestorationSuccessHandler: CompletedTransactionsRestoreCompletion?
/**
Handles completed transaction restoration failure
*/
public var completedTransactionsRestorationFailureHandler: CompletedTransactionsRestoreFailure?
/**
Handles successful downloads restoration
*/
public var downloadsUpdateSuccessHandler: DownloadsUpdateCompletion?
/**
Handles transaction updates
*/
public var transactionsUpdateHandler: TransactionsUpdateCompletion?
/**
Handles transaction removals
*/
public var transactionsRemovalHandler: TransactionsRemovalCompletion?
