I created an xcode project with the same name and I accidentally overwrote the old project

I created an xcode project with the same name and I accidentally overwrote the old project. How do I get it back? All old source is gone and it isn't in the Trash. It has all been replaced with the new开发者_如何学Python project template code.

• If you have backups/source control, you can re-sync your old version.

Back up/shelve what you have now, and leave it checked out/on your system. Then, try to replace just the project file(s), leaving your source code and data in-place. Re-do the changes to your project(s), and you will have undone the damage.

• If you don't have source control or backups, and you didn't delete your code/data, you may still be in luck. You'll have to re-create your project files from scratch, rather than your last save point, but you can simply import your existing code.

• If you don't have any of those, and you deleted the source, then you are out of luck

No matter what, your next step is to get and use source control and/or start doing automatic backups of your code. Everyone makes mistakes like this, and this is why source control/backups exist. You must use them.

From the other discussion, it sounds like your best hope might be an OS X undelete utility, one example:

I hope you've not been doing much with the drive though as any file, email, or anything else you've saved to disk could have been overwriting what used to be there. But, it's better than doing nothing.

I would boot off a separate drive before you downloaded that to run it.
