How can I get vim autocompletion working in iTerm

Question

I recently switched from MacVim to regular Vim in iTerm. I've been encountering an issue where I can't get vim's autocompletion to trigger using Ctrl-N.

Instead, I get iTerm's autocompletion which autocompletes differently than Vim's.

I've tried going into the iTerm preferences and remapping Ctrl-N to ignore. I'm not sure if that's just preventing that input from reaching Vim but it does disable the iTerm autocompletion.

Turns out I had set a shortcut setting in System Preferences that had overridden that key a long time ago and forgot about it. That's what was causing the issue.
