Xcode – How to ask permissions for camera and gallery at the same time in iOS?

I have an app where I need to request gallery access and camera access at the same time on tap of a button.i.e. one after another.I am new to swift. Is there a proper way to do that?

This is my code I am currently using:

func checkPermissions() {
    
    if UIImagePickerController.isSourceTypeAvailable(.photoLibrary) {
        // Request read-write access to the user's photo library.
        PHPhotoLibrary.requestAuthorization(for: .readWrite) { status in
            switch status {
            case .notDetermined:
                // The user hasn't determined this app's access.
                print("Not Determined")
                self.showAlertToOpenSettings(type: 1)
            case .restricted:
                // The system restricted this app's access.
                print("Resticted")
                self.showAlertToOpenSettings(type: 1)
            case .denied:
                // The user explicitly denied this app's access.
                print("Denied")
                self.showAlertToOpenSettings(type: 1)
            case .authorized:
                // The user authorized this app to access Photos data.
                print("authorised")
                DispatchQueue.main.async {
                    self.openPhotoPicker()
                }
            case .limited:
                // The user authorized this app for limited Photos access.
                print("Limited")
                DispatchQueue.main.async {
                    self.showLimitedLibraryAlert()
                }
//                self.openLimitedLibrary()
            @unknown default:
                fatalError()
            }
        }
    }
    if UIImagePickerController.isSourceTypeAvailable(.camera) {
        //Camera
        AVCaptureDevice.requestAccess(for: AVMediaType.video) { response in
            if response {
                //access granted
            } else {
                self.showAlertToOpenSettings(type: 2)
            }
        }
    }
}

The issue with this is that if user selects options from photoLibrary permission alert, the camera alert appears immediately after selecting any option. For example if I select limited option ("Select Photos") then Camera alert appears immediately after over the select photos window.

Please let me know if I am missing anything from my question. I hope it is more clear now.

    first add these lines to info plist

    <key>NSCameraUsageDescription</key>
<string>$(PRODUCT_NAME) would like to access camera!.</string>

    and also this

    <key>NSPhotoLibraryUsageDescription</key>
<string>$(PRODUCT_NAME) would like to access photos.</string>

    after that add this class in your project

    import Photos
import UIKit
public extension PHPhotoLibrary {
static func execute(controller: UIViewController,
                   onAccessHasBeenGranted: @escaping () -> Void,
                   onAccessHasBeenDenied: (() -> Void)? = nil) {

  let onDeniedOrRestricted = onAccessHasBeenDenied ?? {
     let alert = UIAlertController(
        title: "We were unable to load your album groups. Sorry!",
        message: "You can enable access in Privacy Settings",
        preferredStyle: .alert)
     alert.addAction(UIAlertAction(title: "Cancel", style: .cancel, handler: nil))
     alert.addAction(UIAlertAction(title: "Settings", style: .default, handler: { _ in
        if let settingsURL = URL(string: UIApplication.openSettingsURLString) {
           UIApplication.shared.open(settingsURL)
        }
     }))
     controller.present(alert, animated: true)
  }

  let status = PHPhotoLibrary.authorizationStatus()
  switch status {
  case .notDetermined:
     onNotDetermined(onDeniedOrRestricted, onAccessHasBeenGranted)
  case .denied, .restricted:
     onDeniedOrRestricted()
  case .authorized:
     onAccessHasBeenGranted()
  case .limited:
    onAccessHasBeenGranted()
  @unknown default:
     fatalError("PHPhotoLibrary::execute - "Unknown case"")
  }


 }
}

private func onNotDetermined(_ onDeniedOrRestricted: @escaping (()->Void), _ onAuthorized: @escaping (()->Void)) {


PHPhotoLibrary.requestAuthorization({ status in
switch status {
  case .notDetermined:
     onNotDetermined(onDeniedOrRestricted, onAuthorized)
  case .denied, .restricted:
     onDeniedOrRestricted()
  case .authorized:
     onAuthorized()
 case .limited:
    onAuthorized()
  @unknown default:
     fatalError("PHPhotoLibrary::execute - "Unknown case"")
  }
 })
}

    how to use it inside button or viewdidload etc

    PHPhotoLibrary.execute(controller: self, onAccessHasBeenGranted: {
// access granted... 
})

    You can add camera and photo gallery permission both one after another. You just have to add this key in info.plist –

    <key>NSCameraUsageDescription</key> <string>Mention reason to access camera</string>

    <key>NSPhotoLibraryUsageDescription</key>
<string>Mention reason to access photo Library</string>

    and once it is added you have to add the following code in Appdelegate or in view controller you need to ask permission –

    func askForCameraPermission() {
    AVCaptureDevice.requestAccess(for: AVMediaType.video) { response in
            if response {
                //access granted
            } else {

            }
        }        
}

func askForPhotoLibraryPermission() {
    let photos = PHPhotoLibrary.authorizationStatus()
        if photos == .notDetermined {
            PHPhotoLibrary.requestAuthorization({status in
                if status == .authorized{
                    //access granted
                } else {}
            })
        }
}
