Question

Okay,

I have a really weird problem. When switching over to a different XIB, it shows on simulator but not on my test device. I will provide some code and screenshots of my layout in interface builder! Thanks in advance.

• SettingViewController (what get’s called to be displayed)
• DetailViewController (what calls SettingsViewController to be displayed)

Sorry for all the code.

This sort of thing is often due to a difference in file systems: MacOS is typically case-insensitive, while iOS is always case-sensitive. So if you specify the .xib as “myview.xib” but it’s actual name is “MyView.xib”, that’ll generally work on the simulator but not on the device. Same thing happens with images and other resources.
