Some Bug Fixes & Improvements

watchOS & SPM fixes

Fixed issues when compiling for watchOS, with SPM, Xcode 12, and / or Swift 5.3+.

watchOS, discounts, sandbox testing, and more

This update includes some changes and improvements that will (hopefully) fix some common issues as well as expand support for long-awaited features.

New Features

• watchOS support. Apple has introduced in-app purchases on the Apple Watch starting with watchOS 6.2. Now you can use SwiftyStoreKit to take advantage of this additional platform.
• Discount support. Now your app can offer in-app purchase discounts to users through SwiftyStoreKit (#458).
• Cancellable requests. Attempt to cancel requests sent with SwiftyStoreKit.

Improvements & Bug Fixes

• Sandbox purchasing process should be improved. New checks exist to help you identify when a request is being sent in the sandbox and to isolate sandbox-specific errors.
• Added Purchased protocol to create common conformance for Purchase, PurchaseDetails, and ReceiptItem.
• Fixed callback issues when restoring items.
• Added a new API to retrieve all product identifiers, getDistinctPurchaseIds.
• Extended support for your own receipt verification process.
• ReceiptItem now conforms to Codable.
• Additional extensions on existing StoreKit classes for localizedSubscriptionPeriod, localizedPrice, and localizedDiscountPrice.
