如何将摄像头采集的图像传递给第二个视图控制器？斯威夫特

import AVFoundation

class FirstViewController: UIViewController, AVCaptureVideoDataOutputSampleBufferDelegate {
    var captureSession: AVCaptureSession?
    var videoPreviewLayer: AVCaptureVideoPreviewLayer?
    
    override func viewDidLoad() {
        super.viewDidLoad()
        
        // 创建摄像头输入
        guard let captureDevice = AVCaptureDevice.default(for: .video) else { return }
        guard let input = try? AVCaptureDeviceInput(device: captureDevice) else { return }
        
        // 创建摄像头输出
        let output = AVCaptureVideoDataOutput()
        output.setSampleBufferDelegate(self, queue: DispatchQueue(label: "cameraQueue"))
        
        // 创建捕获会话
        captureSession = AVCaptureSession()
        captureSession?.addInput(input)
        captureSession?.addOutput(output)
        
        // 创建视频预览层
        videoPreviewLayer = AVCaptureVideoPreviewLayer(session: captureSession!)
        videoPreviewLayer?.videoGravity = AVLayerVideoGravity.resizeAspectFill
        videoPreviewLayer?.frame = view.layer.bounds
        view.layer.addSublayer(videoPreviewLayer!)
        
        // 启动摄像头捕获会话
        captureSession?.startRunning()
    }
    
    // 捕获摄像头输出的图像数据
    func captureOutput(_ output: AVCaptureOutput, didOutput sampleBuffer: CMSampleBuffer, from connection: AVCaptureConnection) {
        guard let imageBuffer = CMSampleBufferGetImageBuffer(sampleBuffer) else { return }
        
        // 在这里可以对图像进行处理
        
        // 将图像传递给第二个视图控制器
        let secondViewController = SecondViewController()
        secondViewController.image = imageBuffer
        
        // 在这里进行界面切换到第二个视图控制器
        // 例如：self.navigationController?.pushViewController(secondViewController, animated: true)
    }
}

import UIKit

class SecondViewController: UIViewController {
    var image: CVImageBuffer?
    
    override func viewDidLoad() {
        super.viewDidLoad()
        
        if let imageBuffer = image {
            // 将CVImageBuffer转换为UIImage
            let ciImage = CIImage(cvImageBuffer: imageBuffer)
            let context = CIContext()
            if let cgImage = context.createCGImage(ciImage, from: ciImage.extent) {
                let uiImage = UIImage(cgImage: cgImage)
                
                // 在这里使用uiImage显示图像
                // 例如：let imageView = UIImageView(image: uiImage)
                //       self.view.addSubview(imageView)
            }
        }
    }
