I am trying to make a landscape game and trying to display the scene in full screen. However for some reason it is not covering up the whole screen. I see 2 big black bars around the scene. My scene background color is different than the background color of the view. (I am using UIKit) My SKScene Dimensions: 1334x750 View Controller Presentation is set to Full Screen. My app's Requires Full Screen Option is also checked. The scaleMode is .aspectFill I think this is happening since I have updated to iOS 14. Please help me out... Thanks!
