Can anyone tell me how to get code back if changed?

parc

Basically I had a project on the go which had loads of info in it about what the code did etc.

i.e. // This is a frame and this is a stack blah blah blah...


I just deleted loads of this to write another simple bit of code thinking that it would still be there as long as I didn't save over it. When I closed Xcode and reopened it i found that it still had the smaller bit of code even though I didn't save it

How do I get my big piece of code back (tried cmd + z but didn't work)? Thanks

(Btw I'm working in C on Xcode)

Source control? If not, Time Machine (the backup software not a device for travelling through time)?

If none of those, the comments/code is gone. Xcode saves files on exit as you've found.

Most IDEs auto save on run. What you need is git or some other version control as Colonel Panic said. Problem is no one starts to use them until just after a mistake like yours. No version control or time machine and it's gone.
