How to allow user to pick the image with Swift?

Question

I am writing my first iOS application (iPhone only) with Swift. The main application view should allow user to choose the image from the photo gallery.

I've found the following sample code of ViewController.swift:

class ViewController: UIImagePickerController, UINavigationControllerDelegate, UIImagePickerControllerDelegate  {

    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }

    func tableView(tableView: UITableView!, didSelectRowAtIndexPath indexPath: NSIndexPath!) {

        var imagePickerController = UIImagePickerController()
        imagePickerController.delegate = self
        imagePickerController.sourceType = UIImagePickerControllerSourceType.SavedPhotosAlbum
        imagePickerController.allowsEditing = true
        self.presentViewController(imagePickerController, animated: true, completion: { imageP in

        })
    }


    func imagePickerController(picker: UIImagePickerController!, didFinishPickingImage image: UIImage!, editingInfo: NSDictionary!) {
        let selectedImage : UIImage = image
        println(selectedImage)
    }

}

and have the following View Controller Scene -

View Controller
 - Top Layout Guide
 - Bottom Layout Guide
 - View
   - Image View
First Responder
Exit

But when I start the app, just black screen is shown. What I am doing wrong? Another sample code I've found is in Objective-C, which doesn't help me.

One problem could be that didSselectRowAtIndePath is a delegate call for UITableViewDelegate. According to your scene layout and your code there isn't a tableview being used here and your ViewController isn't a UITableViewDelegate. Maybe start will a blank project that works and add a button and fire your code from the button press. — Michael Wildermuth, Aug 26 '14 at 17:44
@LA_ i don't understand why the tableView functions are involved here? — Dekel Maman, Aug 26 '14 at 19:22

If you just want let the user choose image with UIImagePickerController use this code:

import UIKit


class ViewController: UIViewController, UINavigationControllerDelegate, UIImagePickerControllerDelegate {

    @IBOutlet var imageView: UIImageView!
    @IBOutlet var chooseBuuton: UIButton!
    var imagePicker = UIImagePickerController()

    @IBAction func btnClicked() {

        if UIImagePickerController.isSourceTypeAvailable(.savedPhotosAlbum){
            print("Button capture")

            imagePicker.delegate = self
            imagePicker.sourceType = .savedPhotosAlbum
            imagePicker.allowsEditing = false

            present(imagePicker, animated: true, completion: nil)
        }
    }

    func imagePickerController(picker: UIImagePickerController!, didFinishPickingImage image: UIImage!, editingInfo: NSDictionary!){
        self.dismiss(animated: true, completion: { () -> Void in

        })

        imageView.image = image
    }
}

What if I don't want user to press the button to choose the image? – LA_ Aug 26 '14 at 20:25
remove the @IBaction from the func and call the func when ever you want let say in the viewDidLoad or anytime you want just call it – Dekel Maman Aug 26 '14 at 21:52
Thanks. It says `Attempt to present on whose view is not in the window hierarchy!`. Should I add something to the Scene? – LA_ Aug 27 '14 at 08:23

I upvoted bc this was really helpful. Just had to change NSDictionary to [NSObject: AnyObject] and works great! – scubasteve623 Jul 30 '15 at 14:55
@DekelMaman there was a suggested edit in the review queue to make it Swift3, but [it was of poor quality](https://stackoverflow.com/review/suggested-edits/15680221), so I rejected it and made a proper edit to avoid more suggestions – Cœur Mar 30 '17 at 12:50
how can i get the image from gallery ? – Paresh Hirpara Dec 06 '18 at 02:15
@PareshHirpara just use the sourceType for example, imagePicker.sourceType = .savedPhotosAlbum; – Dekel Maman Dec 10 '18 at 14:21

    var viewController: UIViewController?

            UIAlertAction in
        }

        // Add the actions
        picker.delegate = self
        alert.addAction(cameraAction)
        alert.addAction(galleryAction)
        alert.addAction(cancelAction)
    }

    func pickImage(_ viewController: UIViewController, _ callback: @escaping ((UIImage) -> ())) {
        pickImageCallback = callback;
        self.viewController = viewController;

        alert.popoverPresentationController?.sourceView = self.viewController!.view

        viewController.present(alert, animated: true, completion: nil)
    }
    func openCamera(){
        alert.dismiss(animated: true, completion: nil)
        if(UIImagePickerController .isSourceTypeAvailable(.camera)){
            picker.sourceType = .camera
            self.viewController!.present(picker, animated: true, completion: nil)
        } else {
            let alertController: UIAlertController = {
                let controller = UIAlertController(title: "Warning", message: "You don't have camera", preferredStyle: .alert)
                let action = UIAlertAction(title: "OK", style: .default)
                controller.addAction(action)
                return controller

    func openGallery(){
        alert.dismiss(animated: true, completion: nil)
        picker.sourceType = .photoLibrary
        self.viewController!.present(picker, animated: true, completion: nil)
    }

    
    func imagePickerControllerDidCancel(_ picker: UIImagePickerController) {
        picker.dismiss(animated: true, completion: nil)
    }
    //for swift below 4.2
    //func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
    //    picker.dismiss(animated: true, completion: nil)

        picker.dismiss(animated: true, completion: nil)
        guard let image = info[.originalImage] as? UIImage else {
            fatalError("Expected a dictionary containing an image, but was provided the following: \(info)")
        }
        pickImageCallback?(image)
    }



    @objc func imagePickerController(_ picker: UIImagePickerController, pickedImage: UIImage?) {
    }

}

Call it from your viewcontroller like this:

    ImagePickerManager().pickImage(self){ image in
        //here is the image
    }

Also don't forget to include the following keys in your info.plist:

<key>NSCameraUsageDescription</key>
<string>This app requires access to the camera.</string>
<key>NSPhotoLibraryUsageDescription</key>
<string>This app requires access to the photo library.</string>

Had to replace func `imagePickerController` with this to make it work. Thanks! ```func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) { let image = info[UIImagePickerController.InfoKey.originalImage] as! UIImage pickImageCallback?(image) picker.dismiss(animated: true, completion: nil) }``` — Tum, Jan 05 '19 at 20:02

I added the following code to fix the issue: if alert.actions.count > 0 { // alert called again after canceling self.present(alert, animated: true, completion: nil) } else { alert.addAction(cameraAction) alert.addAction(galleryAction) alert.addAction(cancelAction) self.present(alert, animated: true, completion: nil) } — Ing. Ron, Nov 15 '20 at 19:20
@Ing.Ron the addActions need to be set only once, hence they should sit in the init method instead - I've updated the code. Let me know if you get any issues with that — vir us, Nov 15 '20 at 20:20
@vir us: Many thanks for your fast response! In my case I put your init() code in the viewDidLoad() which works fine for me! — Ing. Ron, Nov 15 '20 at 20:38

For Swift 3:

First, you need to add the following key in info.plist:

    <key>NSPhotoLibraryUsageDescription</key>
<string>This app requires access to the photo library.</string>

Your View controller needs to conform to the following protocols: UIImagePickerControllerDelegate, UINavigationControllerDelegate:
```
class ImagePickerViewController:  UIViewController,UIImagePickerControllerDelegate, UINavigationControllerDelegate {}
```

You need to declare the UIImage you will be useing to bind the returned/selected image:

@IBOutlet weak var myImageView: UIImageView!
@IBoutlet weak var upLoadImageBtn:UIImage!
let imagePicker = UIImagePickerController()

Set the pickerImage delegate to be your ViewController:
```
imagePicker.delegate = self
```

For the upload button, you will need to link to the following image in order to fire the action and display the image picker:

@IBAction func upLoadImageBtnPressed(_ sender: AnyObject) {
    imagePicker.allowsEditing = false
    imagePicker.sourceType = .photoLibrary


    /*
    The sourceType property wants a value of the enum named        UIImagePickerControllerSourceType, which gives 3 options:

    UIImagePickerControllerSourceType.PhotoLibrary
    UIImagePickerControllerSourceType.Camera
    UIImagePickerControllerSourceType.SavedPhotosAlbum

    */
    present(imagePicker, animated: true, completion: nil)

}

Your View controller needs to implement the delegate methods for the image picker delegates:

// MARK: - ImagePicker Delegate

func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {

    if let pickedImage = info[UIImagePickerControllerOriginalImage] as? UIImage {
        myImageView.contentMode = .scaleAspectFit
        myImageView.image = pickedImage
    }


    /*

    Swift Dictionary named “info”.  
    We have to unpack it from there with a key asking for what media information we want.
    We just want the image, so that is what we ask for.  For reference, the available options are:

    UIImagePickerControllerMediaType
    UIImagePickerControllerOriginalImage
    UIImagePickerControllerEditedImage
    UIImagePickerControllerCropRect
    UIImagePickerControllerMediaURL
    UIImagePickerControllerReferenceURL
    UIImagePickerControllerMediaMetadata

    */
    dismiss(animated: true, completion: nil)
}

func imagePickerControllerDidCancel(_ picker: UIImagePickerController) {
    dismiss(animated: true, completion:nil)
}

In Swift 5 you have to do this

class ViewController: UIViewController, UIImagePickerControllerDelegate, UINavigationControllerDelegate {

    @IBOutlet var imageView: UIImageView!
    var imagePicker = UIImagePickerController()

    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view.
    }

    @IBAction func setPicture(_ sender: Any) {
        if UIImagePickerController.isSourceTypeAvailable(.photoLibrary){
            imagePicker.delegate = self
            imagePicker.sourceType = .photoLibrary
            imagePicker.allowsEditing = false

            present(imagePicker, animated: true, completion: nil)
        }
    }

    func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {
        picker.dismiss(animated: true, completion: nil)
        if let image = info[UIImagePickerController.InfoKey.originalImage] as? UIImage {
            imageView.image = image
        }

    }

I know this is question is a year old, but here's some pretty simple code (mostly from this tutorial) that's working well for me:

import UIKit

class ViewController: UIViewController, UIImagePickerControllerDelegate, UINavigationControllerDelegate {

@IBOutlet weak var imageView: UIImageView!

var imagePicker = UIImagePickerController()

override func viewDidLoad() {
    super.viewDidLoad()

    self.imagePicker.delegate = self
}

@IBAction func loadImageButtonTapped(sender: AnyObject) {
    print("hey!")
    self.imagePicker.allowsEditing = false
    self.imagePicker.sourceType = .SavedPhotosAlbum

    self.presentViewController(imagePicker, animated: true, completion: nil)
}

func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [NSObject : AnyObject]) {
    if let pickedImage = info[UIImagePickerControllerOriginalImage] as? UIImage {
        self.imageView.contentMode = .ScaleAspectFit
        self.imageView.image = pickedImage
    }

    dismissViewControllerAnimated(true, completion: nil)

}

func imagePickerControllerDidCancel(picker: UIImagePickerController) {
    self.imagePicker = UIImagePickerController()
    dismissViewControllerAnimated(true, completion: nil)
}

Of course, above answers solve the main problem.

I faced a crash in Swift 3.0 while launching the photo album because Info.plist did not had these flags:

Privacy - Photo Library Usage Description -> NSPhotoLibraryUsageDescription
Privacy - Camera Usage Description -> NSCameraUsageDescription

[ screenshot[1]

Please add them if you face similar issue.

Xcode 10, Swift 4.2

Below is a slightly optimized version of the implementation. This is in Swift 4.2 and I have tested it too.

You can see the complete code for ViewController here. Please note that you have to define an IBOutlet (imageView) and IBAction (didTapOnChooseImageButton) defined and connected in storyboard too. Hope this helps.

import UIKit

class ImagePickViewController: UIViewController,UIImagePickerControllerDelegate,UINavigationControllerDelegate {

var imagePicker = UIImagePickerController()
@IBOutlet weak var imageView: UIImageView!

override func viewDidLoad() {
    super.viewDidLoad()
    // Do any additional setup after loading the view.
}

@IBAction func didTapOnChooseImageButton(_ sender: Any) {
    let alert:UIAlertController=UIAlertController(title: "Choose Image", message: nil, preferredStyle: UIAlertController.Style.actionSheet)
    let cameraAction = UIAlertAction(title: "Camera", style: UIAlertAction.Style.default) {
        UIAlertAction in
        self.openCamera(UIImagePickerController.SourceType.camera)
    }
    let gallaryAction = UIAlertAction(title: "Gallary", style: UIAlertAction.Style.default) {
        UIAlertAction in
        self.openCamera(UIImagePickerController.SourceType.photoLibrary)
    }
    let cancelAction = UIAlertAction(title: "Cancel", style: UIAlertAction.Style.cancel) {
        UIAlertAction in
    }

    // Add the actions
    imagePicker.delegate = self as UIImagePickerControllerDelegate & UINavigationControllerDelegate
    alert.addAction(cameraAction)
    alert.addAction(gallaryAction)
    alert.addAction(cancelAction)
    self.present(alert, animated: true, completion: nil)
}

func openCamera(_ sourceType: UIImagePickerController.SourceType) {
    imagePicker.sourceType = sourceType
    self.present(imagePicker, animated: true, completion: nil)
}

//MARK:UIImagePickerControllerDelegate

func imagePickerController(_ picker: UIImagePickerController,
                                    didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {
    imageView.image = info[UIImagePickerController.InfoKey.originalImage] as? UIImage
    imagePicker.dismiss(animated: true, completion: nil)
}

func imagePickerControllerDidCancel(_ picker: UIImagePickerController) {
    print("imagePickerController cancel")
}

}

You can do like here

var avatarImageView = UIImageView()
var imagePicker = UIImagePickerController()
        
func takePhotoFromGallery() {
    imagePicker.delegate = self
    imagePicker.sourceType = .savedPhotosAlbum
    imagePicker.allowsEditing = true
    
    present(imagePicker, animated: true)
}

func imagePickerController(_ picker: UIImagePickerController,
                           didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {
    if let pickedImage = info[.originalImage] as? UIImage {
        avatarImageView.contentMode = .scaleAspectFill
        avatarImageView.image = pickedImage
    }
    self.dismiss(animated: true)
}

Hope this was helpful

here is an easy way to do it:

but first you have to add ( Privacy - Photo Library Usage Description ) in the info.plist, and you should have a button and a UIImageView in your viewController.

then create an outlet of the UIImageView ( in this code the outlet is called myImage), and an action of the button ( I called the action importing in my code )

import UIKit
class ViewController: UIViewController, UIImagePickerControllerDelegate, UINavigationControllerDelegate {

    override func viewDidLoad() {
        super.viewDidLoad()

    }
    @IBOutlet weak var myImage: UIImageView!
    @IBAction func importing(_ sender: Any) {
        let Picker = UIImagePickerController()
        Picker.delegate = self
        Picker.sourceType = .photoLibrary
        self.present(Picker, animated: true, completion: nil)
        Picker.allowsEditing = true
        Picker.mediaTypes = UIImagePickerController.availableMediaTypes(for: .photoLibrary)!
    }

     func imagePickerController(_ picker: UIImagePickerController,didFinishPickingMediaWithInfo info: [String : Any])
    {
        let chosenImage = info[UIImagePickerControllerOriginalImage] as! UIImage //1
        myImage.contentMode = .scaleAspectFit //2
        myImage.image = chosenImage //3
        dismiss(animated:true, completion: nil) //4
    }

}

Incase if you don't want to have a separate button, here is a another way. Attached a gesture on imageView itself, where on tap of image a alert will popup with two option. You will have the option to choose either from gallery/photo library or to cancel the alert.

import UIKit
import CoreData

class AddDetailsViewController: UIViewController, UITextFieldDelegate, UIImagePickerControllerDelegate, UINavigationControllerDelegate {

@IBOutlet weak var imageView: UIImageView!

var picker:UIImagePickerController? = UIImagePickerController()

@IBAction func saveButton(sender: AnyObject) {
    let managedContext = (UIApplication.sharedApplication().delegate as? AppDelegate)!.managedObjectContext

    let entity = NSEntityDescription.entityForName("Person", inManagedObjectContext: managedContext)

    let person = Person(entity: entity!, insertIntoManagedObjectContext: managedContext)

    person.image = UIImageJPEGRepresentation(imageView.image!, 1.0) //imageView.image

    do {
         try person.managedObjectContext?.save()
         //people.append(person)
       } catch let error as NSError {
         print("Could not save \(error)")
    }
}

override func viewDidLoad() {
    super.viewDidLoad()
    let tapGesture = UITapGestureRecognizer(target: self, action: #selector(AddDetailsViewController.tapGesture(_:)))
    imageView.addGestureRecognizer(tapGesture)
    imageView.userInteractionEnabled = true

    picker?.delegate = self
    // Do any additional setup after loading the view.
}

override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
    // Dispose of any resources that can be recreated.
}

func tapGesture(gesture: UIGestureRecognizer) {
    let alert:UIAlertController = UIAlertController(title: "Profile Picture Options", message: nil, preferredStyle: UIAlertControllerStyle.ActionSheet)

    let gallaryAction = UIAlertAction(title: "Open Gallary", style: UIAlertActionStyle.Default) {
        UIAlertAction in self.openGallary()
    }

    let cancelAction = UIAlertAction(title: "Cancel", style: UIAlertActionStyle.Cancel) {
        UIAlertAction in self.cancel()
    }

    alert.addAction(gallaryAction)
    alert.addAction(cancelAction)

    self.presentViewController(alert, animated: true, completion: nil)

}


func openGallary() {
    picker!.allowsEditing = false
    picker!.sourceType = UIImagePickerControllerSourceType.PhotoLibrary
    presentViewController(picker!, animated: true, completion: nil)
}

func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : AnyObject]) {
    if let pickedImage = info[UIImagePickerControllerOriginalImage] as? UIImage {
        imageView.contentMode = .ScaleAspectFit
        imageView.image = pickedImage
    }

    dismissViewControllerAnimated(true, completion: nil)
}

func cancel(){
    print("Cancel Clicked")
}

}

Adding more to the question, implemented the logic to store images in CoreData.

Try this one it's easy.. to Pic a Image using UIImagePickerControllerDelegate

    @objc func masterAction(_ sender: UIButton)
    {
        if UIImagePickerController.isSourceTypeAvailable(.savedPhotosAlbum){
            print("Button capture")

            imagePicker.delegate = self
            imagePicker.sourceType = .savedPhotosAlbum;
            imagePicker.allowsEditing = false

            self.present(imagePicker, animated: true, completion: nil)
        }

        print("hello i'm touch \(sender.tag)")
    }

    func imagePickerControllerDidCancel(_ picker:
        UIImagePickerController) {
        dismiss(animated: true, completion: nil)
    }

    func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
        if let chosenImage = info[UIImagePickerControllerOriginalImage] as? UIImage {
            print("Get Image \(chosenImage)")
            ImageList.insert(chosenImage, at: 0)

If you want to pick only normal image you can use below code,that check that the picked image is not panorama image.

let picker = UIImagePickerController()

func photoFromLibrary() {

        self.picker.allowsEditing = true
        self.picker.sourceType = .photoLibrary
        //picker.mediaTypes = UIImagePickerController.availableMediaTypes(for: .photoLibrary)!

        self.present(self.picker, animated: true, completion: nil)

}

func shootPhoto() {

            if UIImagePickerController.isSourceTypeAvailable(.camera) {
                self.picker.allowsEditing = true
                self.picker.sourceType = UIImagePickerControllerSourceType.camera
                self.picker.cameraCaptureMode = .photo
                self.picker.modalPresentationStyle = .fullScreen
                self.present(self.picker,animated: true,completion: nil)
            }

}

//Image picker delegate
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {

    let str = "\(info["UIImagePickerControllerOriginalImage"]!)"

    let s = str.slice(from: "{", to: "}")

    if let arr = s?.components(separatedBy: ","){
        if arr.count >= 2 {
            if Int(arr[0])! > 11000 {
                picker.dismiss(animated:true, completion: nil)
                self.makeToast("Invalid Image!!!")
                return
            }
                     }
        }
