问题
I am trying to open a cocoa GUI application from authorization plugin which runs during login. I have placed the application in /Library/Application Support/MyFolder/Example.app. I am using below environment and code to open the application.
Environment
OSX: 10.14.5 (Mojave)
Xcode: 11.2.1
Swift: 4.2
Code
let task = Process.init()
task.launchPath = "/Library/Application Support/MyFolder/Example.app/Contents/MacOS/Example"
task.arguments = ["Hi", "Hello"]
task.launch()
task.waitUntilExit()
While the above code works perfectly fine when trying to open process from normal cocoa application it doesn't when I am trying the same from authorization plugin
