                       Fluid Audio is a Swift SDK for fully local, low-latency audio AI on Apple devices,
                       with inference offloaded to the Apple Neural Engine (ANE). The SDK includes
                       state-of-the-art speaker diarization, transcription, and voice activity detection
                       via open-source models that can be integrated with just a few lines of code.

  # iOS Configuration
  # Exclude TTS module from iOS builds to avoid ESpeakNG xcframework linking issues.
  # CocoaPods has known limitations with vendored xcframeworks during pod lib lint on iOS:
  # the framework symbols aren't properly linked in the temporary build environment,
  # causing "Undefined symbols" linker errors even though the binary is valid.
  # iOS builds include: ASR (speech recognition), Diarization, and VAD (voice activity detection).

  # macOS Configuration
  # ESpeakNG framework is only vendored for macOS in the podspec (not a framework limitation).
  # The xcframework supports iOS, but CocoaPods fails to link it during iOS validation.
  # This enables TTS (text-to-speech) functionality with G2P (grapheme-to-phoneme) conversion.
  # macOS builds include: ASR, Diarization, VAD, and TTS with ESpeakNG support.
