SPXConnection crashed when pre-connect for SPXSpeechSynthesizer

[shannonchou]

IN ORDER TO ASSIST YOU, PLEASE PROVIDE THE FOLLOWING:

• Speech SDK log taken from a run that exhibits the reported issue.
  See instructions on how to take logs.

• A stripped down, simplified version of your source code that exhibits the issue. Or, preferably, try to reproduce the problem with one of the public samples in this repository (or a minimally modified version of it), and share the code.

• If relevant, a WAV file of your input audio.

• Additional information as shown below

Describe the bug

var speechConfig: SPXSpeechConfiguration?
var audioConfig: SPXAudioConfiguration?
do {
    let documentsDirectoryPathString = NSSearchPathForDirectoriesInDomains(.documentDirectory, .userDomainMask, true).first!
    let documentsDirectoryPath = NSURL(string: documentsDirectoryPathString)!
    let logFilePath = documentsDirectoryPath.appendingPathComponent("swift.log")
    
    try speechConfig = SPXSpeechConfiguration(subscription: GlobalConfig.audioSub, region: GlobalConfig.audioRegion)
    speechConfig?.setPropertyTo(logFilePath!.absoluteString, by: SPXPropertyId.speechLogFilename)
} catch {
    print("error \(error) happened")
}

speechConfig?.speechSynthesisVoiceName = GlobalConfig.voiceName

let synthesizer = try! SPXSpeechSynthesizer(speechConfiguration: speechConfig!, audioConfiguration: nil)

SPXConnection *connection = [[SPXConnection alloc]initFromSpeechSynthesizer:synthesizer];
[connection open: NO];  // crashed here

It's crashed when call open method.
