How to solve issues between Unity and Xcode?

When testing my app in Unity everything works as it should but, when I test the app on my IPhone the same functionalities that work on my desktop no longer work. For example I have a score system using the Unity UI that works great on desktop. Basically when I hit play on my desktop the 9 digits of zeros go away from the editor, and the points start to count up. On my IPhone the 9 digits stay on the screen and the score does not go up. No clue why that is or how to fix it and any help is appreciated. Thank you for your time!
