Following the earlier launch, I obtained phrase that Apple had added a brand new form of gross sales receipt which is used for IAP testing. This launch provides assist for these.
Modifications
- NEW: Added assist for indefinite size encoding for containers
- NEW: Added assist for decoding date strings with a UTC offset as an alternative of Z.
For first change was finished in DTFoundation which comprises DTASN1, our ASN.1 decoder. When writing an ASN.1 file you’d usually know all lengths of all containers and primitive values and so you can specify the size following every tag. Apple was doing so in all gross sales receipts to this point and we didn’t have any subject with it.
In Xcode 12, Apple added a brand new means of testing In-App purchases (see Introducing StoreKit Testing in Xcode WWDC 2020 discuss for more information). This broke parsing.
They began utilizing indefinite size encoding for numerous container components, together with however not restricted to the PKCS7 container. As soon as I had carried out that, I discovered that additionally they had a sure date with +0300 as timezone, as an alternative of Z (for UTC) as we had beforehand encountered. So I wanted so as to add this variant as properly.
The replace was tagged on GitHub (which additionally serves as new launch for Swift Package deal Supervisor) and can also be obtainable through Cocoapods.
Additionally revealed on Medium.
