暗模式不会在 Xcode 中切换到暗模式背景

Question

I have set up different backgrounds for ' Light/Dark Appearance '

But when switching between Light/Dark mode within Xcode , my background always uses image from ' Any/Light Appearance '. Only colours set for icons changes accordingly.

FYI: I'm switching between Light/Dark mode using Interface Style option.

Can someone please advice what I'm missing on? It's all new to me.

Answer 1

I think it is an Xcode bug. You can confirm it by changing your setting in the iOS Simulator.

Go to Settings -> Developer -> Dark Appearance

Answer 2

I think you might need to uncheck the Resizing checkbox and set the Scales property to Single Scale. It worked for me.

Answer 3

将图像设置为渲染为原始图像

Answer 4

I think it's an Xcode (latest version) bug.

If you run it on your phone, you won't have this problem. Meaning settings are correct.

Answer 5

In Simulator it's working fine. One can confirm by toggling the Appearance from feature menu of the simulator.

Answer 6

这似乎是一个 Xcode 错误，但是当您尝试在模拟器或物理设备上运行它时，假设您处于黑暗模式，它应该可以完美运行。

Answer 7

By unchecking the Preserve Vector Data option 1 , one can see the change in the background when switching between the modes from interface styles 2 .

But I noticed that if you leave the option selected and test it on the simulator, it works perfectly fine there. Hence I feel it's an Xcode bug too.

Answer 8

The Xcode Bug is still here, Xcode storyboard appearance switcher does not work, it only works in the simulator.
You can change the simulator device appearance: Settings> Developer> Dark Appearance.

Happy coding.

Answer 9

On my physical device iPhone 8 iOS 14.6 dark Mode doesn't work. traitCollectionDidChange not get called after switching to dark mode. On my iPhone 12 iOS 15.x, and some testers it works. No Solution i tried worked. Also i got some other weird UI bugs aswell on my iPhone 8.

Hope its just an Xcode Bug.
