Swift has shorthand operators that combine one operator with an assignment, so you can change a variable in place. These look like the existing operators you know –
/, but they have an
= on the end because they assign the result back to whatever variable you were using.
For example, if someone scored 95 in an exam but needs to be penalized 5 points, you could write this:
var score = 95 score -= 5
Similarly, you can add one string to another using
var quote = "The rain in Spain falls mainly on the " quote += "Spaniards"
