iOS Question userInterfaceStyle is always 1 = light mode

[Alexander Stolte]

I'm using the following code to check if the user is using a dark mode or the light mode.
If i have the light mode the result is 1, but if i have the dark mode on, then the returning number is a 1 too.

Public Sub IsDarkMode As Boolean
    Dim app As Application
    If app.OSVersion < 13 Then Return False
    Dim no As NativeObject = app.KeyController
    Return no.GetField("traitCollection").GetField("userInterfaceStyle").AsNumber = 2
End Sub

Dynamic dark and light modes

As Apple is requiring all new apps (in April 2020) to support iOS 13 at a minimum, I'd like to update my app to support the user's system choice of light or dark mode as part of the iOS 13 compatibility. However, I'm not sure how to implement this in b4i. From Apple's documentation, it looks...

Have you added: #PlistExtra: <!--<key>UIUserInterfaceStyle</key>-->
?

Without it, dark mode will be disabled for your app.
