No Way to Set Initial View Controller in New Storyboard in Xcode 6
Solution 1:
Select the view controller, then use the “Is Initial View Controller” checkbox in the attributes inspector.
Solution 2:
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.
Solution 3:
"Is initial View Controller" is back in XCode 6.3.x.
Solution 4:
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.
