Find two maximum numbers from an array

FindTwoMax.swift

import Foundation

func findTwoMax(_ array: [Int]) -> (Int, Int)? {
    guard array.count > 1 else {
        return nil
    }
    
    var max = Int.min
    var secondMax = Int.min
    
    for i in 0..<array.count {
        
        if max < array[i] {
            secondMax = max
            max = array[i]
        }
        else if secondMax < array[i] {
            secondMax = array[i]
        }
    }
    
    return (max, secondMax)
}

// Test
findTwoMax([1,12,3,7,6,5,8,14])
