Have you had experience with implementing dark mode in user interface applications?

In iOS, dark mode support was introduced with iOS 13 to implement dark themes. The main approach is to use adaptive colors and images that automatically change depending on the current interface theme.

For this, you can create colors in the Asset Catalog in Xcode with the "Appearances" setting (Any, Dark), where different values are set for light and dark themes.

In code, you can check the current mode using traitCollection.userInterfaceStyle and update the interface when the theme changes:

override func traitCollectionDidChange(_ previousTraitCollection: UITraitCollection?) {
    super.traitCollectionDidChange(previousTraitCollection)
    if traitCollection.hasDifferentColorAppearance(comparedTo: previousTraitCollection) {
        // Update colors and interface elements
    }
}

Using system colors (e.g., UIColor.label, UIColor.systemBackground) also ensures automatic adaptation to the theme without additional code.
