Kill process in swift

问题

I am trying to make a Mac application that will automatically close a code designated application running on the OS. I am trying to use killall (like in Terminal). Whenever I try to run the program, I get, "sysctl: unknown oid 'killall'".

Here's my code:

let task = Process()
    task.launchPath = "/usr/sbin/sysctl"
    ///usr/sbin/sysctl
    task.arguments = ["killall","iTunes"]
    let pipe = Pipe()
    task.standardOutput = pipe
    task.standardError = pipe
    task.launch()
    task.waitUntilExit()
    let data = pipe.fileHandleForReading.readDataToEndOfFile()
    let output: String = NSString(data: data, encoding: String.Encoding.utf8.rawValue) as! String
    print(output)

Thanks in advance!

I'd suggest you first read the man page for sysctl -- it's used to get and set kernel state. Does that sound like something you want?

The path to killall is /usr/bin/killall, which you can find from Terminal:

> which killall
/usr/bin/killall

Here's the full Swift code:

let pipe = Pipe()

let task = Process()
task.launchPath = "/usr/bin/killall"
task.arguments = ["iTunes"]
task.standardOutput = pipe
task.standardError = pipe
task.launch()
task.waitUntilExit()

let data = pipe.fileHandleForReading.readDataToEndOfFile()
if let output = String(data: data, encoding: .utf8) {
    print(output)
}

my 2 cents: You succeed in killing "iTunes" only if You Xcode App will run with SandoBox DISABLED

All examples on stack overflow about Process are misleading as they call "ls" or "echo" that are always executed ad in system folders.
