I am building a table view app. There are names of some websites on the cells and the webpage of the websites are in detail page. The names and URLs of the websites are saved in Firebase Database. My question is, how to add the websites to the 'favorite"? In the 'favorite' page, I want to see the names on the cell, and the webpage in the detail page. How to make the 'Add to Favorite' button and how the datas are added to the favorite page? Anyone please help me? I will be so grateful if anyone help me with that. I am using Swift and Firebase. Thanks.
