如何从我的Cocoa应用程序运行shell命令？

import Foundation

func executeShellCommand(_ command: String) -> String? {
    let task = Process()
    let pipe = Pipe()
    
    task.standardOutput = pipe
    task.standardError = pipe
    task.arguments = ["-c", command]
    task.launchPath = "/bin/sh"
    task.launch()
    
    let data = pipe.fileHandleForReading.readDataToEndOfFile()
    let output = String(data: data, encoding: .utf8)
    
    return output
}

if let output = executeShellCommand("echo 'Hello, World!'") {
    print("Output: \(output)")
} else {
    print("Error: Unable to execute command")
}

Output: Hello, World!
