How to switch programmatically to dark mode swift

Question

How can I make a switch to change programatically to dark or light mode in my iOS app? I'm using Swift.

You can override the style for single views or view controller using the overrideUserInterfaceStyle property. But since the window is also a view, you can set that on your main window to force it into light or dark mode:

window.overrideUserInterfaceStyle = .dark
