I have been looking for it, but I can’t find the answer. I have a button “photograph”, when pressed, it turns on the camera, you take a photo, when you select “use photo”, I want it to be saved to the photo library.
I can do everything except save to the library People, can anyone help?

This is my code to open the camera:

Use the following code to get the image taken from the photo library and save it in the photo library.

Code Support for Swift 3.1 & 4.0 version:

First of all, we must be in Project. Set permissions in the plist file: –

1)Camera

NSCameraUsageDescription
This app will use camera.

2) Picture library

NSPhotoLibraryUsageDescription
You can select photos to attach to reports.

3) Save to photo library

NSPhotoLibraryAddUsageDescription
< string>Please allow access to save photo in your photo library

We need to open the .pilst file as the source code type, and then add permissions in it-

after

 import UIKit

class ViewController: UIViewController, UINavigationContro llerDelegate, UIImagePickerControllerDelegate {

 @IBOutlet weak var imageTake: UIImageView!

 var imagePicker: UIImagePickerController!
 override func viewDidLoad() {
 super.viewDidLoad ()
 }

 //MARK:-Take image
 @IBAction func takePhoto(_ sender: UIButton) {
 imagePicker = UIImagePickerController()
 imagePicker.delegate = self
 imagePicker.sourceType = .camera
 present(imagePicker, animated: true, completion: nil)
 }

 //MARK:-Saving Image here
 @IBAction func save(_ sender: AnyObject) {
 UIImageWriteToSavedPhotosAlbum(imageTake.image!, self, #selector(image(_:didFinishSavingWithError:contextInfo:)), nil)
 }

 //MARK:-Add image to Library
 func image(_ image: UIImage, didFinishSavingWithError error: Error?, contextInfo: UnsafeRawPointer) {
 if let error = error {
 // we got back an error!
 let ac = UIAlertController(title: "Save error", message: error.localizedDescription, preferredStyle: .alert)
 ac.addAction(UIAlertAction(title: "OK" , style: .default))
 present(ac, animated: true)
} else {
 let ac = UIAlertController(title: "Saved!", message: "Your altered image has been saved to your photos.", preferredStyle: .alert)
 ac.addAction(UIAlertAction(title: "OK", style: .default))
 present(ac, animated: true)
 }
 }

 //MARK:-Done image capture here
 func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String: Any]) {
 imagePicker .dismiss(animated: true, completion: nil)
 imageTake.image = info[UIImagePickerControllerOriginalImage] as? UIImage
 }

}

Swift 4.2 Code update –

class ViewController: UIViewController, UINavigationControllerDelegate {

 @IBOutlet weak var imageTake: UIImageView!
 var imagePicker: UIImagePickerController!

 enum ImageSource {
 case photoLibrary
 case camera
 }

 override func viewDidLoad() {
 super.viewDidLoad()
 }

 //MARK:-Take image
 @IBAction func takePhoto(_ sender: UIButton) {
 guard UIImagePickerController.isSourceTypeAvailable(.camera) else {
 selectImageFrom(.photoLibrary)
 return
 }
 selectImageFrom(.camera)
 }

 func selectImageFrom(_ source: ImageSource){
 imagePicker = UIImagePickerController()
 imagePicker.delegate = self
 switch source {
 case .camera:
 imagePicker.sourceType = .camera
 case .photoLibrary:
 imagePicker.sourceType = .photoLibrary
 }
 present(imagePicker, animated: true, completion: nil)
 }

 //MARK:-Saving Image here
 @IBAction func save(_ sender: AnyObject) {
 guard let selectedImage = imageTake.image else {
 print("Image not found!")
 return
 }< br /> UIImageWriteToSavedPhotosAlbum(selectedImage, self, #selector(image(_:didFinishSavingWithError:contextInfo:)), nil)
 }

 //MARK:-Add image to Library
 @objc func image(_ image: UIImage, didFinishSavingWithError error: Error?, contextInfo: UnsafeRawPointer) {
 if let error = error {
 // we got back an error!
 showAlertWith( title: "Save error", message: error.localizedDescription)
} else {
 showAlertWith(title: "Saved!", message: "Your image has been saved to your photos.")
 }
 }

 func showAlertWith(title: String, message: String){
 let ac = UIAlertController(title: title, message: message, preferredStyle: .alert)
 ac.addAction(UIAlertAction( title: "OK", style: .default))
 present(ac, animated: true)
 }
 }

 extension ViewController: UIImagePickerControllerDelegate{

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

 return

 imageTake.image = selectedImage
