I am creating a new project using latest Xcode (12.1). the default deployment target when I create a new project was 14.1. then I change it to be 11.0. because I want to target users from iOS 11.0 and above
then it will create a lot of warnings like this in my AppDelegate and SceneDelegate
I fix all of them so my AppDelegate and SceneDelegate will be like the code below.
the problem is.....
when I run it on my real device iOS 14.1, it will have no issue. but when I run it on my iOS 12.4.8 , my app will completely dark
I have also already turn off the dark mode in info.plist using this key
<key>Appearance</key>
<string>Light</string>
how to solve this ?
completely dark like this iOS 12.4.8 .the background colour should be custom orange

// This occurs shortly after the scene enters the background, or when its session is discarded.

// The scene may re-connect later, as its session was not necessarily discarded (see `application:didDiscardSceneSessions` instead).
