I am the Lead iOS Developer for The Incc, an upcoming social networking application. The platform offers subscriptions that grant users access to premium content, primarily digital magazines showcasing diverse cultures, alongside standard social media features and additional unique functionalities. I am exploring two specific use cases for our subscription model. Promo Codes with Split Payments: We plan to collaborate with the our influencers (referred to as Mover Shakers) by providing them with promo codes for users to purchase subscriptions. For such purchases, we aim to implement a revenue split model, allocating 10% to the influencer and the remainder to us after Apple’s fees. Gifting Subscriptions: We also wish to enable users to gift subscriptions to others within the app. I understand that the Apple Subscription Service does not natively support these features. What other options do we have to achieve this that are also not against the Apple's guidelines.
