At first my code would not compile, but then I realized I forgot to import the UIKit :)

import UIKit //doing it my way
func distanceFromDeath (heroX: Double, heroY:Double, enemyX:Double, enemyY:Double) -> Double {
    let xDifferenceSquared = pow(heroX - enemyX, 2)
    let yDifferenceSquared = pow(heroY - enemyY, 2)
    let distance = sqrt(xDifferenceSquared + yDifferenceSquared)
    return floor(distance)
}
distanceFromDeath(heroX: towerX, heroY: towerY, enemyX: enemyX, enemyY: enemyY)
