[NSNetService _internalNetService]: unrecognized selector sent to instance

URLSession streamTask with NetService crashes in iOS 14 beta.

Code Block swift func netService(_ sender: NetService, didUpdateTXTRecord data: Data) {
						let session = URLSession(configuration: .default, delegate: self, delegateQueue: nil)
						let streamTask = session.streamTask(with: sender)
						streamTask.resume()
						streamTask.captureStreams()
}

Code Block swift
func netService(_ sender: NetService, didUpdateTXTRecord data: Data) {
let session = URLSession(configuration: .default, delegate: self, delegateQueue: nil)
let streamTask = session.streamTask(with: sender)

streamTask.resume()
streamTask.captureStreams()
}

but this one works fine:

Code Block swiftlet streamTask = session.streamTask(withHostName: sender.hostName!, port: sender.port)

Code Block swift
let streamTask = session.streamTask(withHostName: sender.hostName!, port: sender.port)
