Finding sum of elements in Swift array

Question

What is the easiest (best) way to find the sum of an array of integers in swift? I have an array called multiples and I would like to know the sum of the multiples.

Answer 1

this is my approach about this. however I believe that the best solution is the answer from the user username tbd

var i = 0 
var sum = 0
let example = 0
for elements in multiples{
    i = i + 1
    sum = multiples[ (i- 1)]
    example = sum + example
}
