Updated to Xcode 7.0.1 and Project now has problems

Question

So I uploaded my Xcode 6.1 build to iTunes Connect and the app was approved. Now i'm trying to update the app and I updated to Xcode 7.0.1 and Xcode is giving me problems stating:

(For app I used storyboards and Objective-C)

warning: All interface orientations must be supported unless the app requires full screen.

warning: A launch storyboard or xib must be provided unless the app requires full screen.

- (NSUInteger)supportedInterfaceOrientations {

return (UIInterfaceOrientationMaskPortrait | UIInterfaceOrientationMaskPortraitUpsideDown);
}

What's the new supported interface orientation for iOS 9?

Answer 1

If your app supports multi tasking you need to support all orientations (Portrait up, Portrait Down, Landscape Left, Landscape Right) and a also Launch Screen xib/storyboard.

If you are not interested, you can opt-out by specifying UIRequiresFullScreen key in your info.plist and setting the boolean value to YES. (Read this answer for more about this option)
