Stream connection not receiving data in Xcode 16

The following code used to work perfectly in Xcode 15. (Release mode)

I was able to receive non-zero data from the stream

self.inputStream?.read(&inputbuffer, maxLength: readsize)

However, after switching to Xcode 16, stream always returns 0. The code hasn't changed at all.

I’ve already tried several things to troubleshoot this:

• Changed the scheme settings

• Verified that Info.plist contains proper App Transport Security (ATS) settings, including:

    NSExceptionDomains for my host
  
    NSAllowsArbitraryLoads set to true
  

But none of these made a difference.

private let host = "my host"
private let port = 443
private var inputStream: InputStream?
private var outputStream: OutputStream?

open func connect() {
    
    Stream.getStreamsToHost(withName: host, port: port, inputStream: &self.inputStream, outputStream: &self.outputStream)
    
    if let inputStream = inputStream, let outputStream = outputStream {
        inputStream.delegate = self
        outputStream.delegate = self
        
        CFReadStreamSetDispatchQueue(inputStream, PMMStreamQueue)
        CFWriteStreamSetDispatchQueue(outputStream, PMMStreamQueue)
         
        inputStream.open()
        outputStream.open()
    }
}

func stream(_ aStream: Stream, handle eventCode: Stream.Event) {
    switch eventCode {
    case Stream.Event.endEncountered:
        print("endEncountered")
    case Stream.Event.hasBytesAvailable:
        let readsize = 8192 * 4
        var inputbuffer: [UInt8] = [UInt8](repeating: 0, count: readsize)
        let readBytesCount = self.inputStream?.read(&inputbuffer, maxLength: readsize) ?? 0
        print(readBytesCount)
    default:
        break
    }
}

I'm currently using the Release scheme, and the issue only seems to occur in Release mode under Xcode 16.

Does anyone know how to fix this or what's causing the issue?

Thanks in advance!
