I'm wondering if it's possible to search for a certain line of a text using Xcode's Find & Replace feature, and fully delete the line so not even blank space is left over. Is this possible and if so how?
Copy the line you want to delete, including the newline character at the end of the line(selection should go all the way to the far right side of the editor pane).
Then perform a find and replace; paste the line into the the top field, and leave the replace field blank. Click Replace All.
