Swift has several operators that perform comparison, and these work more or less like you would expect in mathematics.
Let’s start with a couple of example variables so we have something to work with:
let firstScore = 6 let secondScore = 4
There are two operators that check for equality:
== checks two values are the same, and
!= (pronounced “not equals”) checks two values are not the same:
firstScore == secondScore firstScore != secondScore
There are four operators for comparing whether one value is greater than, less than, or equal to another. These are just like in mathematics:
firstScore < secondScore firstScore >= secondScore
Each of these also work with strings, because strings have a natural alphabetical order:
"Taylor" <= "Swift"
