Question

please kindly provide me with a solution.

Thank you.

Answer 1

finally I got my file back. my case, I lost my history of mainStoryboard. (couldn't get any history in Xcode)

solution : open your "file" as "textEditor" -> "Revert to" -> "previous save"

Answer 2

Xcode saves local history of the files but it provides no viewer to see them. You have to open the file with textedit and go "File", "Back to" or "Revert document option" and you will see all the previous revisions.
