Kill process in swift

Question

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)
}
