Hello, I am super new to Swift I have just created my first simple app. However I am already thinking big. My idea is to have a rotation of specific items in my app that all users can see but if one user claims one of the items they are the only one who gets to keep it and can be viewed on their profile, does anyone have any tips on how to attach items to specific users that can be traded even or put back into the rotation. Thank you for the help! and sorry if it is a bad question!
