Edit my iOS Carousel ! Mostly built!

Hello, I am developing an iOS app and have created a carousel in my app. I have attached a photo below. Currently you can swipe through cards and see some of the cards below in a carousel. This already works (somewhat.) I want to change a couple of things though. -The images are currently stored in an array, but I want them to draw from a particular folder. If another image is downloaded into this folder, it should be added automatically to the carousel when I run the app. -Currently, the user swipes through and adds or deletes from the folder, but I'd like to get rid of this function entirely. (The "Don't Keep it" and "Keep it" buttons.) Instead, the carousel should always contain the same number of images as there are in the Main Sprites folder. -The "Don't Keep It" button should be replaced with a "Back" button (the homepage is a map) and the "keep it" button should be replaced to "Something" and it doesnt have to have an action because I will code it myself. I hope this makes sense. I look forward to hearing from some of you. Thank you!
