Adjust the spacing and it should work, the compiler thinks you're trying to force-unwrap(optinals) initialScore..."initialScore!" and "initialScore !"means something different to the compiler. Also, while it still works, you can drop the 

let isWinner : Bool

because the compiler infers that the comparisons are either true or false, thus allowing you to wite more readable cole.

var initialScore = 8

initialScore += 1

let isWinner = (initialScore != 10)
