Within my Mac application, I start a long running process (a local server) as so:

let process = Process()
process.launchPath = "/bin/zsh"
process.arguments = ["-c"] + ["'\(command)'"]
try process.run()

I've noticed that when my app is terminated, the process is not and it keeps running.

How can I make it so that the process is killed when my app is terminated (regardless of how it is terminated, i.e. force quit, kill -9, crash, etc.)?
