Running : - Latest version of Xcode - Catalina 10.15.2 - Base model MacBook Pro 13 inch
I'm having an issue where when I have text in a label show up on the simulator but when I try running it on my iPad, it is just blank. The text is currently being shown on the simulator because that is what I have just typed in on the label on the main.storyboard.
I have tried setting the label text manually by doing myLabel.text = "myText" but that didn't work either. Each device is up to date in terms of the software and I have chosen iOS 13/iPad OS for what software the simulator should run on also. I'm thinking it is just some weird iOS 13 bug because I can't find a fix for it.
On iPad
on Simulator

Please check if Dark mode is enabled or not on the actual device, if it is then try changing the color of the text to something else like: BlackColor because if the text color is labelColor then on devices with dark mode enabled it will appear white.
