read piped data into cli application as an array of UInt8

To read piped data into a CLI application as an array of UInt8, you can use Swift's FileHandle to read from the standard input. Here's a simple example:

import Foundation

// Read data from standard input
let inputData = FileHandle.standardInput.readDataToEndOfFile()

// Convert data to an array of UInt8
let byteArray = [UInt8](inputData)

// Print the byte array
print(byteArray)

This code reads all the data from the standard input until EOF and converts it into an array of UInt8. You can then process this array as needed in your application.

For more advanced use cases, such as real-time processing or working with audio data, you might want to look into the BNNS Graph API, which was discussed in the Support real-time ML inference on the CPU session at WWDC 2024. This session covers how to handle real-time data processing efficiently, which might be relevant depending on your specific requirements.
