iOS Sound.startRecorder(...) returns "Error: Timeouted: Promise<String> was destroyed!"

Before submitting a new issue

• I tested using the latest version of the library, as the bug might be already fixed.
• I tested using a supported version of react native.
• I checked for possible duplicate issues, with possible answers.

Bug summary

I have onStartRecord function which I use to record audio message.
On Android it always works and I don't have any issues.
On iOS simulator it also works, but sometimes( appr. every 4th attempt) it does not and my catch gives me error - "Error: Timeouted: Promise was destroyed!"

export const onStartRecord = async (onErrorHandle: () => void) => {
  const audioSet: AudioSet = {
    // Android-specific settings
    AudioEncoderAndroid: AudioEncoderAndroidType.AAC,
    AudioSourceAndroid: AudioSourceAndroidType.MIC,
    // Common settings automatically applied to the appropriate platform
    AudioSamplingRate: 44100,
    AudioEncodingBitRate: 128000,
    AudioChannels: 1,
  };
  try {
    await Sound.startRecorder(undefined, audioSet, true);
  } catch (e) {
    console.error('onStartRecord error:', e);
    onErrorHandle();
  }
};

Can anyone here could help me understand what could be reason for that? 🙏

Could you change line 62 in Sound.swift to

self.recordingSession?.requestRecordPermission { [weak self] allowed in
    guard let self = self else {
        promise.reject(withError: RuntimeError.error(withMessage: "Instance was deallocated"))
        return
    }

and see if problem resolves?

@hyochan
Sadly it does not resolve problem for me.
I found that it possibly may come from node_modules/react-native-nitro-modules/ios/core/Promise.swift 38-43rd lines. Hope it helps. As I am not familiar with Swift, I can't help here much.

Let me know if I can help you somehow resolve this issue. 🙏

@r-smolonskij I've updated nitromodule to 0.31.1 in 0.2.9. Could you also check this?
