OutputStream.write doesn't send the complete data but only a fixed amount

I'm sending a video via OutputStream.write(_maxLength:) but the write method doesn't send all the data bytes but only a fixed amount every time. The total data count is videoData.count = 7357450 but the bytes written(returned by outputStream.write) is only 131768.

This is the method for writing to output stream.

extension OutputStream {
    func write(data: Data) -> Int {
        return data.withUnsafeBytes { write($0, maxLength: data.count) }
    }
}

Is there something wrong with the code? Is there a way to increase the .write capacity?

Note: This is not related to this question: Writing Data to an NSOutputStream in Swift 3. This question asks how to write while my question is about the limits of writing data.

Okay got it! But make sure there is a limit while writing to any stream, and for that you must read documentation. – Sohil R. Memon Jul 05 '19 at 10:10

You can read this source (http://mirror.informatimago.com/next/developer.apple.com/documentation/Cocoa/Conceptual/Streams/Streams.pdf) and I came to know this https://prnt.sc/oaxyll – Sohil R. Memon Jul 05 '19 at 10:22
