Did you know in Swift programming, we don't need to use semicolons? That's right. You don't need to use them. But... There is an interesting opportunity to use it. Semicolons allow you to combine connected elements into a single line.
import Foundation
func sum(value1: Int, value2: Int) -> Int {
let sum = value1 + value2
return sum
}
let total = sum(value1: 1, value2: 2)
