You have to give proper type. You can not initialize object of type AnyObject. and Obviously with not using AnyObject?.

Uploading an Image with Firebase & Swift (iOS)

Before I start, I would just like to pre-warn that my code is most likely not correct due to me being a beginner at coding with Swift.
I am creating an app for a university project, it is the first large app that I have created and I haven't been coding for very long.
I am having a problem when trying to upload an image whilst creating an account with firebase, I have had the code working previously but I was writing to the database with 'childByAutoId()' which was working fine, however I realised that I needed to be writing to the database and saving it by the users ID instead. After I changed 'childByAutoId()' to 'child(uid)' which is my prefixed variable for the users ID it stopped uploading the images and I can't figure out why. I have tried to go back to when it was working with childByAutoId() but now that isn't working either.
My code:
import UIKit
import Firebase
import FirebaseStorage
class RegisterViewController: UIViewController, UIImagePickerControllerDelegate, UINavigationControllerDelegate {
#IBOutlet weak var profileImage: UIImageView!
#IBOutlet weak var usernameField: UITextField!
#IBOutlet weak var emailField: UITextField!

self.view.addGestureRecognizer(UITapGestureRecognizer(target: self.view, action: #selector(UIView.endEditing(_:))))

datePicker.datePickerMode = UIDatePickerMode.date
datePicker.addTarget(self, action: #selector(RegisterViewController.datePickerValueChanged(sender:)), for: UIControlEvents.valueChanged)
dobField.inputView = datePicker
self.profileImage.layer.cornerRadius = self.profileImage.frame.size.width / 2;
self.profileImage.clipsToBounds = true;
}
#objc func datePickerValueChanged(sender: UIDatePicker) {

To upload img on firebase storage
func uploadImagePic(img1 :UIImage){
var data = NSData()
data = UIImageJPEGRepresentation(img1!, 0.8)! as NSData
// set upload path
let filePath = "\(userid)" // path where you wanted to store img in storage
let metaData = FIRStorageMetadata()
metaData.contentType = "image/jpg"
self.storageRef = FIRStorage.storage().reference()
self.storageRef.child(filePath).put(data as Data, metadata: metaData){(metaData,error) in
if let error = error {
print(error.localizedDescription)
return
}else{
//store downloadURL
let downloadURL = metaData!.downloadURL()!.absoluteString
}
}
}
In order to get the download url from the uploaded file, based on the answer, downloadURL from metaData is now deprecated, so this is the proper way:
storageRef.downloadURL(completion: { (url: URL?, error: Error?) in
print(url?.absoluteString) // <- Your url
})
You should get the download url from the reference that you just created, where you can find the downloadURL with a completion handler.
This is an updated Swift 5 answer:
func uploadImagePic(image: UIImage, name: String, filePath: String) {
guard let imageData: Data = image.jpegData(compressionQuality: 0.1) else {
return
}
let metaDataConfig = StorageMetadata()
metaDataConfig.contentType = "image/jpg"
let storageRef = Storage.storage().reference(withPath: filePath)
storageRef.putData(imageData, metadata: metaDataConfig){ (metaData, error) in
if let error = error {
print(error.localizedDescription)
return
}
storageRef.downloadURL(completion: { (url: URL?, error: Error?) in
print(url?.absoluteString) // <- Download URL
})
}
}

How to Crop iPhone Image in Swift 3 App

I am currently in the process of creating a camera app, however when someone takes a picture and it goes to the the crop screen, it doesn't actually fit it to that specific size. How can I change my code to make it only spit out a 800x800 image?

I don't know of a way to constrain a crop to a particular aspect ratio. Instead I'd suggest creating your own method for cropping images.
I have an app on Github called CropImg that does just that. It doesn't constrain the crop to square, but that would be easy to add.

Unresolved identifier error 'email'

This is related to a previous question that was solved (See here: Sharing variables). I saw nothing that addresses what to do if your variable still isn't being recognized but your code to pass the variable appears solid.
I'm getting an unresolved identifier error 'email' when attempting to utilize a user's email address as part of a file path to upload an image to Firebase Storage. Code is here:

}
#IBAction func uploadButtonWasPressed(sender: AnyObject) {

imagePicker.sourceType = .photoLibrary
imagePicker.mediaTypes = [kUTTypeImage as String, kUTTypeMovie as String]
imagePicker.delegate = self
self.present(imagePicker, animated: true, completion: nil)
}

Error: "use of unresolved identifier"

I am making a face detection app. I have written some code for detection but I am getting an error. Kindly suggest me an alternate solution.
Here is the code, and the error is at line number 3.

}
}

You need to declare it and connect to a UIImageView in storyboard.
#IBOutlet weak var personPic: UIImageView!
This is basic of programming. How can you use something that you haven't declared, right? Ok good luck in your project.

Segue to next view controller after successful sign up

I've searched and searched and searched but not found a solution. The sign up works but will not segue to the next view controller. Heres my code:
import UIKit
import Parse
import Bolts
class SignUpVC: UIViewController, UIImagePickerControllerDelegate, UINavigationControllerDelegate {
#IBOutlet weak var profilePictureIV: UIImageView!
#IBOutlet weak var firstNameTF: UITextField!
#IBOutlet weak var lastNameTF: UITextField!
#IBOutlet weak var newUsernameTF: UITextField!
#IBOutlet weak var newPasswordTF: UITextField!
#IBOutlet weak var emailTF: UITextField!
#IBOutlet weak var phoneNumberTF: UITextField!
#IBAction func setProfilePicture(sender: AnyObject) {
let myPickerController = UIImagePickerController()
myPickerController.delegate = self
myPickerController.sourceType = UIImagePickerControllerSourceType.PhotoLibrary
self.presentViewController(myPickerController, animated: true, completion: nil)
}
#IBAction func signUpButton(sender: AnyObject) {
let spinner: UIActivityIndicatorView = UIActivityIndicatorView(frame: CGRectMake(0, 0, 150, 150)) as UIActivityIndicatorView
if firstNameTF.text != "" && lastNameTF.text != "" && newUsernameTF.text != "" && newPasswordTF.text != "" && emailTF.text != "" && phoneNumberTF.text != "" {
let newUser = PFUser()
if let profilePictureImage = profilePictureIV?.image {
let profilePicture = UIImageJPEGRepresentation(profilePictureImage, 1)!
let profilePictureImageFile = PFFile(data: profilePicture)
newUser["profilePicture"] = profilePictureImageFile
}
newUser["firstName"] = firstNameTF.text
newUser["lastName"] = lastNameTF.text
newUser.username = newUsernameTF.text
newUser.password = newPasswordTF.text
newUser.email = emailTF.text
newUser["phoneNumber"] = phoneNumberTF.text
newUser.signUpInBackgroundWithBlock {
(succeeded: Bool, error: NSError?) -> Void in
if let error = error {
spinner.startAnimating()
self.alert("Opps", textMessage: (error.localizedDescription))
} else {
spinner.startAnimating()
self.alert("Congratualtion!", textMessage: "Success, your account has been created.")
self.performSegueWithIdentifier("showMessages", sender: self)
}
}
} else {
alert("Hmm...", textMessage: "If you want an account, please fill in the blanks.")
}
}
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
override func viewWillAppear(animated: Bool) {
self.navigationController!.navigationBar.hidden = false
}
func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : AnyObject]) {
profilePictureIV.image = info[UIImagePickerControllerOriginalImage] as? UIImage
self.dismissViewControllerAnimated(true, completion: nil)
}
func alert(textTitle: String, textMessage: String) {
let alertController = UIAlertController(title: textTitle, message: textMessage, preferredStyle: .Alert)
alertController.addAction(UIAlertAction(title: "OK", style: .Default, handler: nil))
self.presentViewController(alertController, animated: true, completion: nil)
}
/*
// MARK: - Navigation
// In a storyboard-based application, you will often want to do a little preparation before navigation
override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
// Get the new view controller using segue.destinationViewController.

}
*/
}
If i play the self.performSegueWithIdentifier("showMessages", sender: self) line anywhere else then when i run the program and press the signup button it will directly go to in the messages view controller without any signup required.
as Paulw11 said , Try to remove alert message :-
if let error = error {
spinner.startAnimating()
self.alert("Opps", textMessage: (error.localizedDescription))
} else {
spinner.startAnimating()
self.performSegueWithIdentifier("showMessages", sender: self)
}
or You can call the handler in your code.
if let error = error {
spinner.startAnimating()
self.alert("Opps", textMessage: (error.localizedDescription))
} else {
spinner.startAnimating()
var alert = UIAlertController(title: "Welcome", message: "Login", preferredStyle: UIAlertControllerStyle.Alert)
alert.addAction(UIAlertAction(title:"OK", style: .Default, handler: { action in self.performSegueWithIdentifier("showMessages", sender: self) }
}
You can not pass self as a argument in side the block.
so create a method to call a segue
#IBAction func signUpButton(sender: AnyObject) {
let spinner: UIActivityIndicatorView = UIActivityIndicatorView(frame: CGRectMake(0, 0, 150, 150)) as UIActivityIndicatorView
if firstNameTF.text != "" && lastNameTF.text != "" && newUsernameTF.text != "" && newPasswordTF.text != "" && emailTF.text != "" && phoneNumberTF.text != "" {
let newUser = PFUser()
if let profilePictureImage = profilePictureIV?.image {
let profilePicture = UIImageJPEGRepresentation(profilePictureImage, 1)!
let profilePictureImageFile = PFFile(data: profilePicture)
newUser["profilePicture"] = profilePictureImageFile
}
newUser["firstName"] = firstNameTF.text
newUser["lastName"] = lastNameTF.text
newUser.username = newUsernameTF.text
newUser.password = newPasswordTF.text
newUser.email = emailTF.text
newUser["phoneNumber"] = phoneNumberTF.text
newUser.signUpInBackgroundWithBlock {
(succeeded: Bool, error: NSError?) -> Void in
if let error = error {
spinner.startAnimating()
self.alert("Opps", textMessage: (error.localizedDescription))
} else {
spinner.startAnimating()
self.alert("Congratualtion!", textMessage: "Success, your account has been created.")
callSegue()
}
}
} else {
alert("Hmm...", textMessage: "If you want an account, please fill in the blanks.")
}
}
func callSegue()
{
self.performSegueWithIdentifier("showMessages", sender: self)
}
