i already created the bridge but its hard to understand the documention of ShazamKit . i wonder if there was any idea/help/source code to help me detect music by microphone on a react native application with latest Shazamkit version. thank you.

i tried this but i got the error: Cannot find 'SHMatcher' in scope

// my swift file
import Foundation
import ShazamKit
import AVFoundation
import React

@objc(ShazamBridge)
class ShazamBridge: NSObject {
    private let audioEngine = AVAudioEngine()
    private let session = SHSession()
    private var signatureGenerator = SHSignatureGenerator()

    @objc func startListening(_ resolve: @escaping RCTPromiseResolveBlock, rejecter reject: @escaping RCTPromiseRejectBlock) {
        let inputNode = audioEngine.inputNode
        let recordingFormat = inputNode.outputFormat(forBus: 0)
        inputNode.installTap(onBus: 0, bufferSize: 1024, format: recordingFormat) { (buffer: AVAudioPCMBuffer, when: AVAudioTime) in
            self.signatureGenerator.append(buffer, at: nil)
        }

        audioEngine.prepare()
        do {
            try audioEngine.start()
        } catch {
            reject("Error", "Audio engine could not start", error)
        }

        resolve("Listening started")
    }

    @objc func stopListeningAndIdentify(_ resolve: @escaping RCTPromiseResolveBlock, rejecter reject: @escaping RCTPromiseRejectBlock) {
        audioEngine.stop()
        audioEngine.inputNode.removeTap(onBus: 0)

        let matcher = SHMatcher()
        let signature = signatureGenerator.signature()
        matcher.addSignature(signature)

        session.match(matcher, completion: { (matches, error) in
            if let error = error {
                reject("Error", "Failed to match audio", error)
            } else if let match = matches?.first {
                resolve(match.mediaItem.title)
            } else {
                resolve(nil)
            }
        })
    }
}
