Restart Dock from app

I have an app that needs to restart the dock application. I have tried this with both Apple Script:

var errorDict: NSDictionary? = nil
let appleScript = NSAppleScript(source: "tell application \"Dock\" to quit")
var error = appleScript?.executeAndReturnError(&errorDict)

if let errorDict = errorDict {
    println("An error occured: \(errorDict)")
}

... and NSTask: 

let task = NSTask()
task.launchPath = "/usr/bin/killall"
task.arguments = ["Dock"]
task.launch()

... and another NSTask:

func restartFinder () {
    let task = NSTask()
    task.launchPath = "/bin/bash"
    task.arguments = ["killall Dock"]
    task.launch()
}

However, it seems my app is not allowed to restart it. I'd like to release my app to the AppStore, but how can I restart the dock?

Error when using Apple Script:

An error occured: {
    NSAppleScriptErrorAppName = Dock;
    NSAppleScriptErrorBriefMessage = "Application isn\U2019t running.";
    NSAppleScriptErrorMessage = "Dock got an error: Application isn\U2019t running.";
    NSAppleScriptErrorNumber = "-600";
    NSAppleScriptErrorRange = "NSRange: {27, 4}";
}

Error when using NSTask:

killall: warning: kill -TERM 255: Operation not permitted

Update
I have also tried it with STPrivilegedTask, which didn't work for me either. Neither did I get an auth window.

I would try using Applescript, but instead like this:

var errorDict: NSDictionary? = nil
let appleScript = NSAppleScript(source: "do shell script \"killall Dock\" with administrator " +
"privileges")
var error = appleScript?.executeAndReturnError(&errorDict)

if let errorDict = errorDict {
    println("An error occured: \(errorDict)")
}

This way, it executes the shell script(as if through Terminal) with admin privileges. The problem is since this is a task normally only done by the system or the user, it requires you to type in the admin password.
