Add Array.removeLastTwoIfEmpty() extension for String arrays

[Copilot]

Replaces verbose manual checks for removing trailing empty arguments with a single-line extension method.

Implementation

Added removeLastTwoIfEmpty() to extensions.swift:

extension Array where Element == String {
    mutating func removeLastTwoIfEmpty() {
        let count = self.count
        guard count >= 2,
              self[count - 1].isEmpty,
              self[count - 2].isEmpty else {
            return
        }
        removeLast(2)
    }
}

Usage

Before:

var arguments = ["--verbose", "--archive", "", ""]
let count = arguments.count
if count >= 2 {
    if arguments[count - 1].isEmpty, arguments[count - 2].isEmpty {
        arguments.removeLast()
        arguments.removeLast()
    }
}

After:

var arguments = ["--verbose", "--archive", "", ""]
arguments.removeLastTwoIfEmpty()

Bounds-checked, type-safe, and available project-wide.

Original prompt

how can I easily remove the two last argumenst from an array: if arguments[count - 1].isEmpty, arguments[count - 2].isEmpty {

            }
