ShazamKit during AVCaptureSession - Recognize audio while using camera
Hi, I want to implement ShazamKit in my project. But I have some problems. I use AVCaptureSession to take photos in my app and I'm unable to use ShazamKit. I tried to use three different ways Use an AVAudioEngine during my AVCaptureSession But I didn't obtain any result from Shazam. Try to use ShazamKit after stopping my AvCaptureSession but this causes some problems, and some crashes. Try to use the buffer of my AVCaptureSession to catch audio directly without use AVAudioEngine. This is the code that I use with AVAudioEngine: try! audioSession.setActive(true, options: .notifyOthersOnDeactivation)                 let inputNode = self.audioEngine.inputNode                 let recordingFormat = inputNode.outputFormat(forBus: 0)                                 let audioFormat = recordingFormat //AVAudioFormat(standardFormatWithSampleRate: self.audioEngine.inputNode.outputFormat(forBus: 0).sampleRate,                     //                            channels: 1)                                  inputNode.installTap(onBus: 0, bufferSize: 1024, format: audioFormat) { (buffer: AVAudioPCMBuffer, when: AVAudioTime) in                     try! self.signatureGenerator.append(buffer, at: nil)                                          self.session.matchStreamingBuffer(buffer, at: nil)                 }                              self.audioEngine.prepare()                 try! self.audioEngine.start() I can choose two ways to do this, use AVCaptureSession output to pass it to ShazamKit or use an AVAudioSession after the stop of AVCaptureSession. So I have two questions: Can I use a CMSampleBufferRef from AVCaptureSession buffer in a SHSession? And if the answer is yes how? How can I prevent this error if I want to use an AVAudioSession after I stopped my AVCaptureSession? [aurioc]            AURemoteIO.cpp:1117  failed: -10851 (enable 1, outf< 2 ch,      0 Hz, Float32, deinterleaved> inf< 2 ch,      0 Hz, Float32, deinterleaved>) [avae]            AVAEInternal.h:76    required condition is false: [AVAEGraphNode.mm:834:CreateRecordingTap: (IsFormatSampleRateAndChannelCountValid(format))] *** Terminating app due to uncaught exception 'com.apple.coreaudio.avfaudio', reason: 'required condition is false: IsFormatSampleRateAndChannelCountValid(format)' Thanks

Xcode 12 beta 4 - Unable to upload to TestFlight
I'm attempting to upload a beta of my app for iOS 14 to TestFlight distribution. While Xcode trying to upload the ipa it show an error "App Store Connect Operation Error - An error occurred uploading to the App Store." How can I solve it ? I also tried to use "Transporter" but I can't login in the app for this error "This action cannot be completed at this time (-22411)" Thanks
