Here is the function for toggle camera:-
public func toggleCamera() {
do {
// Access device manager cameras directly, catching any potential nil
let availableCameras = try sharedState.deviceManager!.cameras

      // Define scaling mode for the preview view
      let scalingMode: ScalingMode = .crop

      // Initialize local video streams if nil
      if (sharedState.localVideoStreams == nil) {
          sharedState.localVideoStreams = [LocalVideoStream]()
      }
    if(sharedState.isUsingFrontCamera){
      // Create and append local video stream from first available camera
      let localVideoStream = LocalVideoStream(camera: availableCameras.first{ $0.cameraFacing == .back }!)
      sharedState.localVideoStreams!.append(localVideoStream)
      
      // Create preview renderer and view for the local video stream
      sharedState.previewRenderer = try VideoStreamRenderer(localVideoStream: sharedState.localVideoStreams!.first!)
      sharedState.previewView = try sharedState.previewRenderer!.createView(withOptions: CreateViewOptions(scalingMode: scalingMode))
      sharedState.isUsingFrontCamera.toggle()
    }else{
      let localVideoStream = LocalVideoStream(camera: availableCameras.first{ $0.cameraFacing == .front }!)
      sharedState.localVideoStreams!.append(localVideoStream)
      
      // Create preview renderer and view for the local video stream
      sharedState.previewRenderer = try VideoStreamRenderer(localVideoStream: sharedState.localVideoStreams!.first!)
      sharedState.previewView = try sharedState.previewRenderer!.createView(withOptions: CreateViewOptions(scalingMode: scalingMode))
      sharedState.isUsingFrontCamera.toggle()
    }

      // Start video stream with error handling
      sharedState.call!.startVideo(stream: sharedState.localVideoStreams!.first!) { (error) in
          if (error != nil) {
              sharedState.alertMessage = "Could not share video"
              sharedState.showAlert = true
          }
          else {
              sharedState.sendingLocalVideo = true
          }
      }
  } catch let error {
      // Handle any errors caught during the process
      sharedState.alertMessage = "Error toggling camera: \(error.localizedDescription)"
      sharedState.showAlert = true
  }
