I'm new to the topic of iOS auto renewable subscriptions, and I'm trying to understand 2 things:
- Is it possible to work with subscriptions without a server? If my only goal for now is simply to understand if the subscription is active or not.
- Is it possible to use promotional offers without a server?
In Apple docs they always mention a server-side component for receipt validation, but, at the same time, I see libraries like SwiftyStoreKit, which have methods for subscription validation. So, #1 seems possible. But then maybe #2 is possible, too?
I suspect, without server-side validation malicious users may be able to fake a subscription somehow, but is that all I'd need to worry about?
