5:26 - Configure the AVCaptureSession

import AVFoundation

private let session = AVCaptureSession()
private func configureSession() {
    session.beginConfiguration()
    session.sessionPreset = .photo
}

6:11 - Configure AVCapturePhotoOutput

import AVFoundation

private let photoOutput = AVCapturePhotoOutput()
private let configurePhotoOutput: () -> Void = {
    photoOutput.maxPhotoQualityPrioritization = .quality // or .balanced
}

6:38 - Add maxPhotoDimensions to AVCapturePhotoOutput

import AVFoundation

let supportedMaxPhotoDimensions = device?.activeFormat.supportedMaxPhotoDimensions ?? []
if let largestDimension = supportedMaxPhotoDimensions.max(by: { lhs, rhs in
    Int(lhs.width) * Int(lhs.height) < Int(rhs.width) * Int(rhs.height)
} ) {
    photoOutput?.maxPhotoDimensions = largestDimension
}

session?.commitConfiguration()
session?.startRunning()

7:21 - Update AVCapturePhotoSettings

import AVFoundation

let settings = AVCapturePhotoSettings()
settings.maxPhotoDimensions = dimension.cmVideoDimensionsValue
settings.photoQualityPrioritization = .quality

var delegate: AVCapturePhotoCaptureDelegate?

// Configure photo request delegate

if let delegate {
 photoOutput?.capturePhoto(with: settings, delegate: delegate)
}

8:59 - Prepare resources for the capture

import AVFoundation

let prepareSettings = AVCapturePhotoSettings()
prepareSettings.maxPhotoDimensions = photoOutput.maxPhotoDimensions
prepareSettings.photoQualityPrioritization = .quality

photoOutput.setPreparedPhotoSettingsArray([prepareSettings]) { prepared, error in
  if let error = error {
    print("Failed to prepare: \(error)")
      return
  }
  print("Pipeline prepared: \(prepared)")
}

// Later, when ready to capture — create NEW settings
let captureSettings = AVCapturePhotoSettings()
captureSettings.maxPhotoDimensions = photoOutput.maxPhotoDimensions
captureSettings.photoQualityPrioritization = quality
photoOutput.capturePhoto(with: captureSettings, delegate: self)
