Find min / max value in Swift Array

arrays, swift

Solution

Given:

let numbers = [1, 2, 3, 4, 5]

Swift 3:

numbers.min() // equals 1
numbers.max() // equals 5

Swift 2:

numbers.minElement() // equals 1
numbers.maxElement() // equals 5

Problem

Given an array of Swift numeric values, how can I find the minimum and maximum values? I've so far got a simple (but potentially expensive) way: ``` var myMax = sort(myArray,>)[0] ``` And how I was taught to do it at school: ``` var myMax = 0 for i in 0..myArray.count { if (myArray[i] > myMax){myMax = myArray[i]} } ``` Is there a better way to get the minimum or maximum value from an integer Array in Swift? Ideally something that's one line such as Ruby's `.min` and `.max`.
