Does anyone know the easy way to check if the user already purchased a subscription or not when the app loads?
I just need to check if the user already purchased the subscription, nothing else. Seems easy, but it is not in reality, because I need to validate a receipt and check a subscription date.... The subscription validation technique seems to be not an easy task and I didn't find a good tutorial or a good guide that describes how to implement it step by step. I've read Apple documentation here Is there any easy Local Receipt Validation and Subscription Validation technique to check if the user subscribed or not?
Maybe anyone knows a framework or a method to do it fast? Any help appreciated.
Using: Swift 4, Xcode 9.4
