title: Storyboard not updating its design in latest version of xcode
body: <p>I am working on a project in Xcode and I made few changes to my storyboard design (mostly the font style and placeholder text and the text on the buttons). It shows the changes in the storyboard but when I run and build the project to the simulator, it still shows the old design and doesn't show the updated storyboard designs. I tried quitting Xcode and also did restart my MacBook but it still doesn't show the updated designs when I run it in simulator. Is there anything I missed or did wrong ? I am working on the latest version of Xcode.</p>
