(Temporary Fix: just reopen the file to add code / changes!)
"The document “filename” could not be saved. You don’t have permission."
Steps I made to get the error:
1. Open Textastic
2. Press CMD + N to get a new window
3. Type some code
4. Press CMD + S to save
5. Now add some new code to the already written ..
6. Try to save again
The folders I was trying to save the file to was #1 desktop and #2 downloads, folders that belong to my user-account so I do have permission to them. :)
