I am sorry to compare to C# but that's the language I know. In C#, I could do something like
process.OutputDataReceived += new DataReceivedEventHandler(MyOutputHandler);
And then I could read the change in realtime. How can I achieve that in Swift MacOS app?
Try AsyncBytes, you can find the documentation here
AsyncBytes isn’t a great option for reading from pipes. Personally, I use Dispatch I/O for this. You can find a read-to-EOF example in Running a Child Process with Standard Input and Output on DevForums. Adapting that to deliver results as they arrive… well… it’s somewhere between easy and hard (-:
