Kuidas saada Swiftis kogu Int-tüüpi massiivi kõigi arvude summa?

In Swift, to obtain the sum of all numbers in an array of type Int, you can use the reduce method, which accumulates the array's values into a single final value.

Example:

let numbers = [1, 2, 3, 4, 5]
let sum = numbers.reduce(0, +)
print(sum) // Will output 15

Here, reduce(0, +) means we start from 0 and sequentially add all the elements of the array. This is a simple and efficient way to get the sum of the array elements.
