Add another 'Camera' Library


⚠️ This project is unmaintained


A camera view controller with custom image picker and image cropping.

camera cropper library permissions


  • [x] Front facing and rear facing camera
  • [x] Simple and clean look
  • [x] Custom image picker with permission checking
  • [x] Image cropping
  • [x] Flash light
  • [x] Zoom
  • [x] Tap to focus

Installation & Requirements

This project requires Xcode 9 to run and compiles with swift 4

Note: This library makes use of the AVFoundation camera API's which are unavailable on the iOS simulator. You'll need a real device to run it.

CocoaPods: Add the following to your Podfile:

pod 'ALCameraViewController'

For swift 3.2 support

pod 'ALCameraViewController', '~> 2.0.3'


github "alexlittlejohn/ALCameraViewController"

Privacy (iOS 10)

If you are building your app with iOS 10 or newer, you need to add two privacy keys to your app to allow the usage of the camera and photo library, or your app will crash.

Add the keys below to your Info.plist, adding strings with the description you want to provide when prompting the user.



To use this component couldn't be simpler. Add import ALCameraViewController to the top of your controller file.

In the viewController

let cameraViewController = CameraViewController { [weak self] image, asset in
    // Do something with your image here.
    self?.dismiss(animated: true, completion: nil)

present(cameraViewController, animated: true, completion: nil)


There are a number of configurable options available for CameraViewController

init(croppingParameters: CroppingParameters = CroppingParameters(),
     allowsLibraryAccess: Bool = true,
     allowsSwapCameraOrientation: Bool = true,
     allowVolumeButtonCapture: Bool = true,
     completion: @escaping CameraViewCompletion)

The Cropping Parameters struct accepts the following parameters

init(isEnabled: Bool = false,
     allowResizing: Bool = true,
     allowMoving: Bool = true,
     minimumSize: CGSize = CGSize(width: 60, height: 60))

The success parameter returns a UIImage? and a PHAsset? for more advanced use cases. If the user canceled photo capture then both of these options will be nil

typealias CameraViewCompletion = (UIImage?, PHAsset?) -> Void

Note: To prevent retain cycles, it is best to use a [weak self] reference within the success parameter

Other usage options

You can also instantiate the image picker component by itself as well.

let croppingEnabled = true

/// Provides an image picker wrapped inside a UINavigationController instance
let imagePickerViewController = CameraViewController.imagePickerViewController(croppingEnabled: croppingEnabled) { [weak self] image, asset in
        // Do something with your image here.
        // If cropping is enabled this image will be the cropped version

    self?.dismiss(animated: true, completion: nil)

present(imagePickerViewController, animated: true, completion: nil)

For more control you can create it directly.

Note: This approach requires some familiarity with the PhotoKit library provided by apple

import Photos

let imagePickerViewController = PhotoLibraryViewController()
imagePickerViewController.onSelectionComplete = { asset in

        // The asset could be nil if the user doesn't select anything
        guard let asset = asset else {

    // Provides a PHAsset object
        // Retrieve a UIImage from a PHAsset using
        let options = PHImageRequestOptions()
    options.deliveryMode = .highQualityFormat
    options.isNetworkAccessAllowed = true

        PHImageManager.default().requestImage(for: asset, targetSize: PHImageManagerMaximumSize, contentMode: .aspectFill, options: options) { image, _ in
        if let image = image {
                        // Do something with your image here

present(imagePickerViewController, animated: true, completion: nil)
