imageView可以显示实时视频吗？(iOS)

import AVFoundation

class ViewController: UIViewController {
    var captureSession: AVCaptureSession?
    var videoPreviewLayer: AVCaptureVideoPreviewLayer?
    
    override func viewDidLoad() {
        super.viewDidLoad()
        
        // 创建捕捉会话
        captureSession = AVCaptureSession()
        
        // 设置视频输入设备
        guard let captureDevice = AVCaptureDevice.default(for: .video) else { return }
        guard let input = try? AVCaptureDeviceInput(device: captureDevice) else { return }
        captureSession?.addInput(input)
        
        // 创建预览图层
        videoPreviewLayer = AVCaptureVideoPreviewLayer(session: captureSession!)
        videoPreviewLayer?.videoGravity = AVLayerVideoGravity.resizeAspectFill
        videoPreviewLayer?.frame = imageView.bounds
        imageView.layer.addSublayer(videoPreviewLayer!)
        
        // 启动会话
        captureSession?.startRunning()
    }
}
