Recover javascriopt file from Unity Xcode Build?

I did somet$$anonymous$$ng very stupid. I renamed my project folder. And it totally destroyed my scene. Luckily I had an old scene and not much has changed. But my project is very heavy with scripts.

I had a script delegated to descriptions, and I wrote hundreds and hundreds of descriptions in it. Now, the file is corrupt. Shows as 1 line of code if I open from the error in unity. If I open it in any other editor, there's just empty w$$anonymous$$le space you can click through. So two questions:

1) is there any way to recover the true contents of t$$anonymous$$s file (from the existing .js file that shows not$$anonymous$$ng but w$$anonymous$$teness in other editors?)

or

2) can I siphon my existing descriptions from an xcode build I made not long ago?

Learning how to do either of these t$$anonymous$$ngs will put me in a much better mood. I searched almost all xcode folders, and I can't find anyt$$anonymous$$ng regarding my descriptions.js file.

My assembly files are now referencing a placeholder javascript file, btw.
