By default, Xcode 7 creates a Main.storyboard file instead of a MainWindow.xib file for newly-created iOS projects. The UIMainStoryboardFile key in the Info.plist file points to the application's main storyboard name (without the extension). When the application starts up, the Main.storyboard file is loaded instead of the NSMainNib entry. Prior versions of Xcode allowed developers to opt in or out of storyboards, but with Xcode 7, storyboards are the default and developers cannot easily opt out. It is still possible to use the xib files for individual sections of an application or to use them to load custom classes for prototype table cells. In addition, Xcode 7 creates a LaunchScreen.storyboard to display as a splash screen (on iOS 8 and higher) while the application is loading, in preference to prerendered screens at fixed resolutions. This allows devices with many different resolutions (including future unannounced ones) to render pixel-perfect splash screens...
