Correct way to find max in an Array in Swift

Question

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:

Answer 1

In Swift 2.0, the minElement and maxElement become methods of SequenceType protocol, you should call them like:

let a = [1, 2, 3]
print(a.maxElement()) //3
print(a.minElement()) //1

Using maxElement as a function like maxElement(a) is unavailable now.

The syntax of Swift is in flux, so I can just confirm this in Xcode version7 beta6.

It may be modified in the future, so I suggest that you'd better check the doc before you use these methods.
