ios – IBM Watson Speech To Text：无法使用swift sdk转录文本

我正在使用IBM Watson语音来发送iOS sdk来转录实时音频.我已经通过可可豆荚安装了它.在将音频转录为文本时,我遇到了问题(身份验证).

已安装的STT sdk版本为0.38.1.@H_675_7@

我已经配置了所有内容,正确创建了服务和凭据,并确保使用正确的apikey和URL实例化SpeechToText.每当我调用startStreaming方法时,STT sdk会打印一些错误日志,这似乎与身份验证挑战有关.@H_675_7@

这是代码片段.@H_675_7@

let speechToText = SpeechToText(apiKey: Credentials.SpeechToTextAPIKey,iamUrl: Credentials.SpeechToTextURL)
var accumulator = SpeechRecognitionResultsAccumulator()

func startStreaming() {

  var setTings = RecognitionSetTings(contentType: "audio/ogg;codecs=opus")
  setTings.interimResults = true
  let failure = { (error: Error) in print(error) }
  speechToText.recognizeMicrophone(setTings: setTings,failure: failurE) { results in
  accumulator.add(results: results)
  print(accumulator.bestTranscript)

 }
}

错误日志@H_675_7@

CredStore - performQuery - Error copying matching creds.  Error=-25300,query={
class = inet;
"m_Limit" = "m_LimitAll";
ptcl = htps;
"r_Attributes" = 1;
sdmn = "IBM Watson Gateway(Log-in)";
srvr = "gateway-syd.watsonplatform.net";
sync = syna;
}

我已经挖掘了IBM Watson sdk文档,甚至用Google搜索了这个问题,但没有找到任何相关的答案.@H_675_7@

任何帮助将受到高度赞赏.@H_675_7@
