如何在IOS AVFoundation中以纵向模式保存/捕获照片？Xcode 10.2 Swift 5

import AVFoundation

func capturePhoto() {
    let captureSession = AVCaptureSession()
    
    guard let captureDevice = AVCaptureDevice.default(for: .video) else {
        print("Failed to get the camera device")
        return
    }
    
    guard let input = try? AVCaptureDeviceInput(device: captureDevice) else {
        print("Failed to create input device")
        return
    }
    
    let photoOutput = AVCapturePhotoOutput()
    
    if captureSession.canAddInput(input) && captureSession.canAddOutput(photoOutput) {
        captureSession.addInput(input)
        captureSession.addOutput(photoOutput)
        
        let photoSettings = AVCapturePhotoSettings()
        photoSettings.isHighResolutionPhotoEnabled = true
        photoSettings.flashMode = .auto
        
        if let connection = photoOutput.connection(with: .video) {
            connection.videoOrientation = .portrait
        }
        
        photoOutput.capturePhoto(with: photoSettings, delegate: self)
    }
}

extension YourViewController: AVCapturePhotoCaptureDelegate {
    func photoOutput(_ output: AVCapturePhotoOutput, didFinishProcessingPhoto photo: AVCapturePhoto, error: Error?) {
        if let imageData = photo.fileDataRepresentation() {
            if let image = UIImage(data: imageData) {
                // 处理照片
                // ...
                
                // 保存照片到相册
                UIImageWriteToSavedPhotosAlbum(image, nil, nil, nil)
            }
        }
    }
}
