Use this property to access the file’s contents as an asynchronous sequence of bytes.

// Asynchronously access the attachment's bytes.
var data = Data()
do {
    for try await byte in dataReader.bytes {
        // Use the bytes here.
        data.append(byte)
    }
} catch {
    // Handle the error here.
    fatalError("*** An error occurred while reading the attachment's data: \(error.localizedDescription) ***")
