I need help calling an array of data from Firebase to post onto a tableView in swift .

Good Afternoon, I need help calling data from firebase to post onto a tableView and collectionView in swift. I can successfully call the data, but it duplicates itself instead of having a single post. I will show an image. please use keyword fruit salad at the top of your post so I know you are serious. You must also have Zoom and I will allow you to control my screen because I would like to see what I was doing wrong. I am very big on communication and I would appreciate it if my freelancer was as well. I will show what I am talking about below.
