Continuous update of long shell command execution

Good morning

To run a shell command works fine on macOS with Sift 5.6....fine so far...

func callShell(_ command: String) throws -> String {
      let task = Process()
      let pipe = Pipe()

      task.standardOutput = pipe
      task.standardError = pipe
      task.arguments = ["-c", command]
      task.executableURL = URL(fileURLWithPath: "/bin/zsh")
      task.standardInput = nil

      try task.run()

      let data = pipe.fileHandleForReading.readDataToEndOfFile()
      let output = String(data: data, encoding: .utf8)!

      return output
  }

But...if I have to execute a shell command that takes a longer time which outputs current state of execution line by line....is there a way to update the output on SwiftUI line by line as well?

Sort of a console log view....or readDataToEndOfLine if it would exist....but then again the function would return at first EOL.

thanks in advance

Ah bugger......

zsh:1: operation not permitted: /opt/homebrew/bin/python3

Seems no way to use external commands under Swift/SwiftUI....back to Xojo then....
