[iOS] Add support for Promoted IAPs handling (shouldAddStorePayment method)

[hasanfd]

Description

Problem Statement
Our app, which is designed specifically for children, is facing repeated rejections during the Apple App Review process. The issue arises from the automatic processing of promoted in-app purchases by the Adapty SDK. When a user taps on a promoted IAP in the App Store, the purchase flow is immediately triggered without any parental verification. This behavior violates Apple’s guidelines for kids apps—where a parental gate is mandatory—resulting in our app being rejected.

Feature Request
Short Term:
Please add an option in the Adapty SDK (or via a configuration setting in the Adapty Dashboard) to disable the automatic processing of promoted in-app purchases. When this option is enabled, tapping on a promoted IAP should not immediately trigger the purchase flow. Instead, it should allow our app to decide when to initiate the purchase (for example, after displaying a custom parental gate).

Long Term:
In a future update, it would be ideal if Adapty could offer built-in parental gate functionality—such as a birthday check or similar verification method—so that apps targeting children can ensure that the purchase process is secured and complies with Apple’s guidelines without requiring a custom workaround.

Benefits
Compliance: This change would help apps in the kids category meet Apple’s strict parental control guidelines, reducing the risk of app rejections.
Developer Control: Disabling automatic behavior gives developers full control over the purchase process, allowing them to implement their own safety measures.
Integrated Solution: In the long term, built-in parental gate options would simplify development and provide a consistent, secure experience for apps designed for children.

Hi @hasanfd! Thank you for the issue! I am not sure if we will add “built-in parental gate functionality” soon, but I will pass your feature request to our product team. For now, I think we are going to expose the shouldAddStorePayment delegate method, similar to iOS, so you can decide whether you want to interrupt the process or not.
