Hello all!

My application written with C++ and using StoreKit1. For now my application using bridge C++/Objective-CPP/Objective-C/Swift. Since StoreKit1 declared "deprecated" got a question of how to implement correctly StoreKit2 in C++ application, mostly everything about Renewable Subscriptions. StoreKit2 have no direct API in Objective-C, it's available only in Swift. Which is the way the best and correct way:

-- for on-device writing C library and in it implement Swift? In this case how to add correctly StoreKit2 into library itself?

-- for on-device somehow write kind of wrapper for Swift StoreKit 2 within translation of all of objects in Objective-C and implement it with C++/Objective-CPP bridge? In this case how to add correctly StoreKit2 in C++ project written with CMake? Here https://github.com/compnerd/swift-cmake-examples/tree/main the one of the examples of interoperability C++/Swift with CMake. But how to use exactly with StoreKit2?

-- only using server side solution?

I had the same issue.

My solution was to write about 200 lines of Swift to do the SK2 stuff, and call that from the C++ code using the Swift/C++ interop. This wasn’t too painful. Start with example code from WWDC.

Could you share link on example code from WWDC? This one https://developer.apple.com/videos/play/wwdc2023/10172?

No, I was referring to a video about using StoreKit2, specifically in my case it was one about using the SubscriptionStoreView.

Which minimal version of XCode allowing this functionality???

I'm currently using xCode 15.1 and I don't recall having to change anything from the defaults to make this work.
