I copied my source code files for the next version of my app. When I open the copied project in Xcode, the controls are hidden and are not being displayed in viewcontrols in storyboard, but when I am running, all controls are appearing in simulator and device.
I am using Xcode 6.4
Change it height and width to its original which was it before.
