Core data displaying images - ios

Question

I am building an iOS application for my year 12 project and it entails users being able to record information about a bill they have received and having the ability to take a photo of the bill and to save it. I have used core data for my users data to be saved to. I have currently been able to get the photo taken by the user to be able to be seen on a seperate screen when the user selects a bill. Where I am having trouble is that the YouTube video I used has only shown me how to display only 1 specific photo in position zero, as shown on line 39. I need help in getting a different image being displayed dependent on what bill the user selects. For example, if a user taps a water bill, on the viewing screen, they will see a water bill. Then if the user taps a gas bill, on the viewing screen, they will see the gas bill. Currently, what is happening is regardless of whether the user selects the gas or water bill, a water bill is displayed. I have tried to explain this the best I can, if there are any other concerns, please let me know.
Thank you for your assistance
