Is here a simple way to pick image and upload it?

Question

I am calling to all swift developers here. I am struggling last 3 days with this topic. Is there a way to pick an image from image picker (local photo library of iPhone) and upload it to server? I can't figure out how to do this....just tons of outdated code or nothin.

You need to do some research before posting questions like this, there is plenty of documentation on the web and on Apple Developer site for learning coding. — RichAppz, Nov 12 '15 at 11:04

You should try to use a UIImagePickerController like this

@IBAction func takePhoto(sender: UIButton) {

    let picker = UIImagePickerController()
    picker.delegate = self;
    picker.allowsEditing = true;
    picker.sourceType = .PhotoLibrary;

    self.presentViewController(picker animated:true completion:nil); 
}

Then you can get the image in imagePickerController(_:didFinishPickingMediaWithInfo:) method from UIImagePickerControllerDelegate

func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : AnyObject]) {
    let chosenImage = info[UIImagePickerControllerEditedImage] as! UIImage
    UploadImage(chosenImage)

    picker.dismissViewControllerAnimated(true, completion: nil);
}

func imagePickerControllerDidCancel(picker: UIImagePickerController) {
    picker.dismissViewControllerAnimated(true, completion: nil);
}

Finally you upload the image. Example using HTTP POST Check this answer

function UploadImage(image : UIImage) {
    var imageData = UIImagePNGRepresentation(image)
    if imageData == nil {
        print("image not valid")
        return
    }

    // Upload
    ....
}
