Type 'UIImagePickerControllerSourceType' has no member 'photoLibrary' - ios

Question

This is the code:
// Only allow photos to be picked,not taken.
imagePickerController.sourceType = .photoLibrary
this is the error: Type 'UIImagePickerControllerSourceType' has no member 'photoLibrary'
Just trying to complete the official tutorial Start Developing iOS Apps (Swift)
//MARK: Actions
#IBAction func selectImageFromPhotoLibrary(sender: UITapGestureRecognizer) {
//Hide the keyboard.
nameTextField.resignFirstResponder()
// UIImagepickerController is a view controller that lets a user pick media from their photo library.
let imagePickerController = UIImagePickerController()
// Only allow photos to be picked,not taken.
imagePickerController.sourceType = .photoLibrary
//Make sure ViewController is notified when the user picks an image.
imagePickerController.delegate = self
present(imagePickerController, animated: true, competion: nil)
}
#IBAction func setDefaultLabelText(sender: UIButton) {
mealNameLabel.text = "Default Text"
}
}

Okay, it looks like you are probably usingSwift 2.2 (maybe it's this for Swift 2.3 also). You want this syntax:
imagePickerController.sourceType = .PhotoLibrary
Note the capitalization. Keep in mind, Xcode 8.2 (released 12 December 2016) will be the last version of Xcode to support Swift 2.x. Sometime in 2017 you will probably need to use Swift 3 for new App Store submissions.
EDIT:
Here's my full Swift 2.2 code, followed by my Swift 3.0 code. Please note two things:
I'm also using the Camera app and have checks to make sure it's present - which isn't the case for the simulator.
Your app will crash in iOS 10 unless you add the following to your info.plist file:
NSCameraUsageDescription
Used to capture new image for photo effect
NSPhotoLibraryUsageDescription
Used to select an image for photo effect
You may put different values in the tags.
Swift 2.2:
let picker = UIImagePickerController()
override func viewDidLoad() {
super.viewDidLoad()
picker.delegate = self
}
extension SelectViewController: UIImagePickerControllerDelegate, UINavigationControllerDelegate {
// MARK: Camera App
func openCameraApp() {
if UIImagePickerController.availableCaptureModesForCameraDevice(.Rear) != nil {
picker.allowsEditing = false
picker.sourceType = UIImagePickerControllerSourceType.Camera
picker.cameraCaptureMode = .Photo
picker.modalPresentationStyle = .FullScreen
presentViewController(picker,
animated: true,
completion: nil)
} else {
noCamera()
}
}
func noCamera(){
let alertVC = UIAlertController(
title: "No Camera",
message: "Sorry, this device has no camera",
preferredStyle: .Alert)
let okAction = UIAlertAction(
title: "OK",
style:.Default,
handler: nil)
alertVC.addAction(okAction)
presentViewController(
alertVC,
animated: true,
completion: nil)
}
// MARK: Photos Albums
func showImagePicker() {
picker.allowsEditing = false
picker.sourceType = .PhotoLibrary
// picker.modalPresentationStyle = .Popover
presentViewController(picker,
animated: true,
completion: nil)
picker.popoverPresentationController?.sourceView = self.view
}
func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : AnyObject]) {
let chosenImage = info[UIImagePickerControllerOriginalImage] as! UIImage
image = chosenImage
self.performSegueWithIdentifier("ShowEditView", sender: self)
dismissViewControllerAnimated(true, completion: nil)
}
func imagePickerControllerDidCancel(picker: UIImagePickerController) {
dismissViewControllerAnimated(false, completion: nil)
}
// MARK: Seque to EditViewController
override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
if segue.identifier == "ShowEditView" {
if let vc = segue.destinationViewController as? EditViewController {
vc.image = image
}
}
}
}
Swift 3.0 (only the extension code has syntax changes):
func openCameraApp() {
if UIImagePickerController.availableCaptureModes(for: .rear) != nil {
picker.allowsEditing = false
picker.sourceType = UIImagePickerControllerSourceType.camera
picker.cameraCaptureMode = .photo
picker.modalPresentationStyle = .fullScreen
present(picker,
animated: true,
completion: nil)
} else {
noCamera()
}
}
func noCamera(){
let alertVC = UIAlertController(
title: "No Camera",
message: "Sorry, this device has no camera",
preferredStyle: .alert)
let okAction = UIAlertAction(
title: "OK",
style:.default,
handler: nil)
alertVC.addAction(okAction)
present(
alertVC,
animated: true,
completion: nil)
}
// MARK: Photos Albums
func showImagePicker() {
picker.allowsEditing = false
picker.sourceType = .photoLibrary
// picker.modalPresentationStyle = .Popover
present(picker,
animated: true,
completion: nil)
picker.popoverPresentationController?.sourceView = self.view
}
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
let chosenImage = info[UIImagePickerControllerOriginalImage] as! UIImage
image = chosenImage
self.performSegue(withIdentifier: "ShowEditView", sender: self)
dismiss(animated: true, completion: nil)
}
func imagePickerControllerDidCancel(_ picker: UIImagePickerController) {
dismiss(animated: false, completion: nil)
}
// MARK: Seque to EditViewController
override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
if segue.identifier == "ShowEditView" {
if let vc = segue.destination as? EditViewController {
vc.image = image
// vc.image = images[0]
}
}
}
