Swift Process() and Xojo Shell

Question

A question for someone who speaks both Swift and Xojo…

As shell objects in Xojo can be run both synchronously and asynchronously, how can a Swift Process() be run the same way?

With Xojo I can run a shell and respond accordingly when data is received from the process being run, thus not locking up the UI during long processes.

With Swift I only know how to run a Process() and handle the resulting data in one lump.

Can anyone who is familiar with Swift Process() please offer me any insights?

In swift you can run the process in the dispatch queue async.

DispatchQueue.main.async {
  // your task here
}

DispatchQueue.global(qos: .userInitiated).async {
 // your task here
}

DispatchQueue.global(qos: .background).async {
 // your task here
}

In your case I would recommend searching on GitHub for swift "shell" packages.
If you don't want to use packages you will find a lot of examples when searching for DispatchQueue async.
