为什么标签上的文字不会出现在实际设备上，而会出现在模拟器中？ (Xcode)

Question

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

请检查实际设备上是否enabled Dark mode ，如果是，则尝试将文本颜色更改为其他颜色： BlackColor因为如果文本颜色是labelColor那么在启用暗模式的设备上它会显示为white 。
