This sample project shows how to use NSXPCConnection to communicate between an AppSandboxed app and its associated login item. After launching, the user will get a window with a text input field in which they can enter questions for which a yes/no response is warranted. The application then passes these questions to a login item that responds with an entertaining answer to the question. This sample is intended to demonstrate the mechanics of interprocess communication between AppSandboxed processes.
