In game Store to buy levels with real money

Hi, I have been looking for some information to create a store in Game, to sell some levels or package on the game through the apple ID. I’m working on a IOS game.

Can somebody help me with this, with a guideline to create this in game system? . I will be very grateful with any advise about this.

Thank you so much.

You will probably be better off asking this on the Apple developer forums and reading up in the SDK how to do these sort of things in relation to the app store.

Thank you, I will do that, however I think I should use some tool or API from Unity to integrate with the apple store.

Thank you.
