Hi Claude, Thanks for the response. Here is the info you requested: Xcode version: 12.5.1 Sim or Device: The issue occurs on both iOS: 14.5 Changed the button programmatically: No I havent touched the navigation bar in some time. It's weird as the back button was working fine up until last week and I have been working on this app for well over 4 years. I checked the debug view hierarchy and couldn't see the back button being blocked by any element. It's strange as the issue seems to be occurring on all back buttons in my app, not just this one specifically. I actually noticed that the issue is currently in the live version of my app on the app store. So you can see it for yourself if you download it. https://apps.apple.com/gb/app/rpg-sounds-fantasy/id1205984620 It will occur on any of the back buttons in the navigation bars. I just tried a navigation controller in a brand new project and it worked fine. Thanks again! And sorry I accidentally selected your answer and the correct answer!

Hi Rincewind, I can do that, but my project is fairly large. Will I be able to submit? Also, is there anyway to un-accept an answer in a thread? I accidentally accepted Claude's response as an answer.

Claude, you're a genius. I completely forgot that a week ago I made a UIButton extension. After commenting the extension out the back button works as normal. Thank you so much for your help!

This worked for me! Thanks Arroz!
