I have read the First Book from appcoda "Beginning programming with Swift"
One feature that I learned in said book and that I really liked while working with storyboards is the ability to refactor some storyboards when the amount of storyboards becomes too large, so at first I was doing it successfully, no problem whatsoever.
I began dividing my storyboards into smaller chunks like so
As soon as I pressed "refactor to storyboards" it didn't prompt me for a name as it did before but instead it renamed the new storyboard reference to "Main copy.storyboard"
When that happened, the old storyboard dissapeared and an exact copy of the main.storyboard appeared
CTROL-Z Did not work as I tried that immediately and I haven't versioned for the past 2 days or so (I know, that was really stupid)
If I can not recover the storyboard, can someone tell me why did this happen? I don't want to do this again
Btw, I am running the last version of XCode 7.2.1
Xcode may have put the lost storyboard in the Trash. Use the Finder to check. The Trash is the wastebasket-looking thing at the right or bottom end of the Dock.
If the lost file is in the Trash, you may be able to right-click it and choose “Put Back” to send it back into your project folder. You may also need to add it back to your project in Xcode using File > Add Files to “MyProject”.
