    Same solution in Swift

    func arrayManipulation(n: Int, queries: [[Int]]) -> Int {

    var arr = Array(repeating: 0, count: n+1)
queries.forEach{
    let a = $0[0]
    let b = $0[1]
    let k = $0[2]

    arr[a-1] += k
    arr[b] -= k
}

let reducedArr = arr.reduce(into: (0,0), { result, number in
    result.0 += number
    result.1 = max(result.1, result.0)

})
return reducedArr.1

    }
