Here\'s what I did in Xcode 6.0.1:
Step 1: Create a new project with a single view.
In Xcode 6, use a "Storyboard Entry Point" from the object library. Drag the control onto the View Controller you wish to designate as the initial View Controller.
Select the view controller, then use the “Is Initial View Controller” checkbox in the attributes inspector.
The Story Entry Point does not exist in Object Library in Xcode 6.x, and cannot upgrade to Xcode 6.3.x for now in china.
"Is initial View Controller" is back in XCode 6.3.x.
In Xcode 6.2, there is no longer an "Is Initial View Controller" checkbox in the attributes inspector. Instead, you set the initial view controller by adding the Storyboard Entry Point found in the Object Library.
