Preview Does not Work
My code does not seem to work when I press PREVIEW, but when I press CHECK WORK, it says the code is correct. So there is nothing wrong with my code. Why is the PREVIEW button not work?
var initialScore = 8 let totalScore = ++initialScore let isWinner = totalScore != 10

The preview works but usually just shows errors so the output is usually blank if your code compiles correctly. Just to try it out, try entering this...
var initialScore = 8 let totalScore = ++initialScore let isWinner = totalScore != 10 let isWinner = false
...and look at the preview. Since this code is trying to declare the isWinner constant twice, this is an error and the preview will show you this.
