ios13 - How can I check whether dark mode is enabled in iOS/iPadOS?

Question

Starting from iOS/iPadOS 13, a dark user interface style is available, similar to the dark mode introduced in macOS Mojave. How can I check whether the user has enabled the system-wide dark mode?

Answer 1

For iOS 13, you can use this property to check if current style is dark mode or not:

if #available(iOS 13.0, *) {
    if UITraitCollection.current.userInterfaceStyle == .dark {
        print("Dark mode")
    }
    else {
        print("Light mode")
    }
}
