I just updated to XCode 8.2.1, when I enter some text in the standard find->text->containing project search box, instead of doing the search, it is creating a new line when I hit "return" (the text I entered scrolls up, you can only see a couple pixels of it, but you can tell its there and up arrow gets you back to that line). I have never seen XCode do this before. I'm thinking it is some silly setting somewhere or something simple I am missing, but as far as I know I didn't change any settings, and I'm not sure what I need to do to fix this. I have already tried rebooting the mac, and closing/re-opening XCode which did not help. I searched stackoverflow and google but couldn't find a solution.
For what it's worth, if I'm running a project in debug mode, with debug console window does the same exact thing, if I type "po myVariable" [return] instead of showing me the value of myVariable, it just creates a new line as if it thinks I want to keep entering text instead of submitting the command I already entered.
Put a pic of this here.
