Launch Sudo Command from MACos App Swift

How to execute a shell command with root permission from swift

Quick-and-dirty:

NSAppleScript(source: "do shell script \"sudo whatever\" with administrator " +
    "privileges")!.executeAndReturnError(nil)

Alternatively look into privileged helper tools but expect that to be much more complicated.

Run a terminal command in a Mac app with Swift Xcode

Try this and let me know if it works. You should do this on a background thread using dispatch_async or NSOperationQueue. For more information on how to do stuff using Grand Central Dispatch read my post: http://manavgabhawala.me/#/blog/grand-central-dispatch

let task = NSTask()
task.launchPath = "/usr/sbin/sysctl"
task.arguments = ["-w", "net.inet.tcp.delayed_ack=0"]
let pipe = NSPipe()
task.standardOutput = pipe
task.standardError = pipe
task.launch()
task.waitUntilExit()
let data = pipe.fileHandleForReading.readDataToEndOfFile()
let output: String = NSString(data: data, encoding: NSUTF8StringEncoding) as! String

Also please can you update the question to include the exact error and the code you are using with NSTask if this doesn't work. Now this won't have the sudo effect that you wanted if you want that look at: https://developer.apple.com/library/mac/documentation/Security/Conceptual/authorization_concepts/01introduction/introduction.html which tells you about how to use sudo. For an unsandboxed app you could also do the same thing as above but change the launchPath to /bin/sh and then add an argument "-S" and also add the argument "/usr/sbin/sysctl". Then you can use standardInput to pipe in the password of the user who has root access. All password entry errors will come in the standard error pipe. Let me know if this works.

How to run a macOS app as root and use system calls?

You want to run as root, or you want to run with sudo? There's a difference. Running as root is definitely not recommended, you will get strange behaviour from the system.

You wrote:

I've tried opening the app with sudo

That should work. How have you tried? You need to call the binary within the .app bundle. Running open against the bundle won't work.

e.g.

sudo ./Xcode.app/Contents/MacOS/Xcode

How to use Process Class to execute commands need to enter password in MacOS

I found the solution by using "STPrivilegedTask" which is a tool to get authorization by users.
Using FileManager API I think also a good idea
