Hi, I finally managed to upload my App to the Apple store, now I am faced with a problem that I don't know how to solve: I would like the customer to be able to download my app and try it for a few days, if it satisfies his needs he can purchase it through an annual subscription with automatic renewal. Searching on the Apple store I found that I should use StoreKit 2, I don't even know how and where to start, surely someone of you has already faced this problem and will be able to help me.
