It would be great if dyci can also work for the change of nib file or storyboard

Sure, why don't we give a try? :)
But you need to be more specific what exactly you're trying to achieve
Xibs are seems to be working now, and storyboards.. There's plenty of possible user cases, so I need exact one :)
So, try to describe the task, or (that would be awesome), if you can attach small test project, that will help to check injection flow

Yes,inject for nib works, but not for storyboard, I try to attach the project ,but It failed! the hint is "Unfortunately we don't support that file type yet" , so I attach an image

look at the image ,I create a static tableviewCell in the tableview which is in storyboard, when the test project is running ,I change tableviewCell's subview's (look athe the image, the label) property,such as font,background color, then press ^X,but failed
