What is going on lol. It's been like this since Xcode 13 on a fresh MBP M1 Max 64g ram -- but going back to 2011 stuff like this was never really a problem with a successful build (and as you can see by the log on the right side, it's successful)
Edit to add, since it's unclear as to what my question was:
Here is that SAME CODE, but in another project:
Notice how the syntax highlighting is different. Why is it "broken" in the Playground?
