Build an app for entertainment seekers

The app connects the user to a database of possible entertainments and tourist attractions each demonstrated in a couple of photos and only few words. Possible entertainments are suggested to the users based on the filters pre-selected (location proximity, price range, duration etc.). The user can swipe right if he likes to know more about the entertainment offered or swipe left if not interested. When the user swipes right, a more detailed page around the product will be sent to his email address or the user page. Email address of the user will not be shared with the product providers.
The app is to be written in Swift (for iphones.).
Optional: You can use PHP for service query.
