In xcode (7.3.1) storyboard, when we click on the assistant editor and select previewthe story panels, we get the result of the storyboard design. At the top there is a lock button, when I click on it, it receives xxx.stroryboard is currently locked because it is a remote resourceand cannot unlock. I also had other questions. 1) I could add options such as iphone 4.4,4.7,3.5 inches, but I could not remove them after adding. How to remove them? 2) I could not move the preview screen to view it and enlarge it because there are no horizontal and vertical scroll bars. How can I scroll it?
