Release notes - iOS 1.23

New functionality

With this release of the iOS library, you can use three new methods to fetch data from previous transactions. These allow you to reprint a receipt, or confirm the final state of a transaction following a connection loss between the cash register and payment terminal.

These methods are:

• fetchLastTransactionsDataWithCount - Fetches data for a specified number of transactions. Provide the count parameter, specifying the number of transactions to fetch.
• fetchLastTransactionDataWithCompletion - Fetches data for the last completed transaction.
• fetchTransactionDataWithTenderReference - Fetches data for a specific transaction. Provide the tenderReference parameter, specifying the tender reference for the transaction.

Fixed issue

In some cases additionalData was not returned when a transaction was completed. This has now been fixed.
