💬 풀이

func solution(_ absolutes:[Int], _ signs:[Bool]) -> Int {
    var result = 0
    
    for (index, absolute) in absolutes.enumerated() {
        result += signs[index] == false ? -absolute : absolute
    }
    
    return result
}

💬 더 나은 방법?

func solution(_ absolutes:[Int], _ signs:[Bool]) -> Int {
    return (0..<absolutes.count).map { signs[$0] ? absolutes[$0] : -absolutes[$0] }.reduce(0, +)
}
