Searching in Xcode not finding results (searching my source)

Question

I'm pulling my hair out on this and Google results are skewed since it thinks I want to find out how to code something.

My problem is that when trying to search my code with the String Matching box it finds nothing, even if I enter something that is on the screen below.

Is it Spotlight that is delivering these results? I'm not excluding anything in my Spotlight index so should I just rebuild the index?

At the top of the Xcode search field, you probably want to select:

Find > Text > Containing

rather than any of:

Find > Text > Matching
Find > References > Matching
Find > References > Containing

I did not (knowingly) switch this to "Text Matching" or "References", but there it was set. "Text Containing" is a more useful search type for most searches.
