I'm using a sample of code as a starting point for my project but, apparently, the option to have Xcode check the syntax and show warnings/errors as I type is turned off.
As a result I have to hit CMD+B (build) many times and it's slowing me down.
I looked at all the places I could think of that could have project settings (that feature is enabled on another project I'm working on so that's telling me it's not an Xcode-wide option) but came up empty.
