Swift 5 with iOS 13

Common solution which is work for my whole application without perform any file specific changes.

Work for Xcode 11 or higher version, Build upload fail on prior version of Xcode 11.

Set UIUserInterfaceStyle to 1 in your info.plist file.

OR

AppDelegate.swift

    if #available(iOS 13.0, *) {
        window?.overrideUserInterfaceStyle = .light
    } else {
        // Fallback on earlier versions
    }

We have to specify user interface style light for any existing application.

This could help you.

override func viewDidLoad() {
    super.viewDidLoad()
    if #available(iOS 13.0, *) {
        // Always adopt a light interface style.
        overrideUserInterfaceStyle = .light
    }
}
