Unchecking "Use Size Classes" option and then coming back and re-checking it again fixes this issue.

• In the project navigator, select a storyboard or xib file.
• The file’s contents open in Interface Builder.
• Choose View > Utilities > Show File Inspector.
• In the Interface Builder Document section, un-tick the "Use Size Classes" checkbox.
• Leave the menu. Come back and tick the "Use Size Classes" checkbox again.
