I turned on the preference setting "xcode "highlight instances of selected symbol" not working" so symbols would highlight with the underline. I have the project NewtonsCradle open and the file NewtonCradle.swift open. When I select a symbol inside of a function it doesn't highlight the other occurences. I have seen it work with other files but I can't reproduce it. I changed the file and saved it to make sure it was wrightable thinking that was the problem. Also the Refactor items are all greyed out.
