I do not know the context of the assignment and if you have been exposed to loops and functions yet, but here are some things to help:

  • the initialScore should probably be the same value (0) in every case. If so, it might be a good idea to change the var into a let here.

  • if the totalScore is calculated more than once, you will have to change it from a constant to a variable. As the value stored is in that case subject to change. You could also consider dropping initialScore and just using 'var totalScore' to store the score at all times and set it to 0 initially.

  • let isWinner = 10 != 10 always results in false because 10 is equal to 10. Perhaps you want to compare the totalScore with the value 10?

Example:

var totalScore = 0

... 
 // some logics that adds points to the score like
totalScore += 10
...

let  isWinner = totalScore == 10 // true
