Is it possible to opt-out of dark mode on iOS 13?

Question

A large part of my app consists of web views to provide functionality not yet available through native implementations. The web team has no plans to implement a dark theme for the website. As such, my app will look a bit half/half with Dark Mode support on iOS 13.

Is it possible to opt out of Dark Mode support such that our app always shows light mode to match the website theme?

Answer 1

Here are a few tips and tricks which you can use in your app to support or bypass the dark mode.

First tip: To override the ViewController style

you can override the interface style of UIViewController by

1: overrideUserInterfaceStyle = .dark //For dark mode

2: overrideUserInterfaceStyle = .light //For light mode

class ViewController: UIViewController {
    override func viewDidLoad() {
        super.viewDidLoad()
        overrideUserInterfaceStyle = .light    
    }
}

Second tip: Adding a key in info.plist

Simply you can add a new key

UIUserInterfaceStyle

in your app info.plist and set its value to Light or Dark. this will override the app default style to the value you provide. You don't have to add overrideUserInterfaceStyle = .light this line in every viewController, just one line in info.plist that’s it.
