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

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
