I am trying to request permission using the function:
func requestPermission() {
CKContainer.default().requestApplicationPermission([.userDiscoverability]) { [weak self] returnedStatus,
returnedError in
DispatchQueue.main.async {
if returnedStatus == .granted {
self?.permissionStatus = true
}
}
}
}
but it is not requesting permission in the simulator. I am signed into iCloud and it is still not working. Any ideas?
Looks like your container name is not same as bundle name, so CKContainer.default() is not working properly.

I have implemented a sign up/ sign in feature using AWS Amplify and swift using my own View controllers instead of the Drop-in auth. The problem starts once I quit the app and restart it. After I do that the user is no longer signed in. I have set remember devices to always in the User Pool Settings. Has anyone ever encountered this problem?
Here is my function where the user gets confirmed and everything works properly except for remembering the user
#objc func confirm(){
print("confirm pressed")
guard let verificationCode = verificationTextField.text else{
return
}
AWSMobileClient.default().confirmSignUp(username: username, confirmationCode: verificationCode) { (signUpResult, error) in
if let signUpResult = signUpResult{
switch(signUpResult.signUpConfirmationState){
case .confirmed:
AWSMobileClient.default().deviceOperations.updateStatus(remembered: true) { (result, error) in //This is where I try to save the users device
print("User is signed up and confirmed")
DispatchQueue.main.async {
let signedInTabBar = SignedInTabBarController()
self.view.window!.rootViewController = signedInTabBar
}
}
case .unconfirmed:
print("User is not confirmed and needs verification via \(signUpResult.codeDeliveryDetails!.deliveryMedium) sent at \(signUpResult.codeDeliveryDetails!.destination!)")
case.unknown:
print("Unexpected case")
}
}else if let error = error {
print("\(error.localizedDescription)")
}
}
}
As I right understand you need to check if a user signed in or not. To do this you need to add this code on the start of the app or wherever you check a user status:
AWSMobileClient.default().initialize { userState, error in
OperationQueue.main.addOperation {
if let error = error {
AWSMobileClient.default().signOut()
assertionFailure("Logic after init error: \(error.localizedDescription)")
}
guard let userState = userState else {
AWSMobileClient.default().signOut()
return
}
guard userState == .signedIn else {
return
}
}
}
I am developing an app in swift, and I use AWS mobile services for authentication and AWS Lambda to do some backend processing. I had everything working fine, and one day (after leaving the app for a month or so), it started throwing this error:
GetId failed. Error is [Error Domain=com.amazonaws.AWSCognitoIdentityProviderErrorDomain Code=-1000 "Authentication delegate not set" UserInfo {NSLocalizedDescription=Authentication delegate not set}]
Unable to refresh. Error is [Error Domain=com.amazonaws.AWSCognitoIdentityProviderErrorDomain Code=-1000 "Authentication delegate not set"
It's killing me, because it was already working. What could have changed?
In appDelegate, I have:
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey : Any]? = nil) -> Bool {
// Uncomment to turn on logging, look for "Welcome to AWS!" to confirm success
AWSDDLog.add(AWSDDTTYLogger.sharedInstance)
AWSDDLog.sharedInstance.logLevel = .error
// Instantiate AWSMobileClient to get AWS user credentials
return AWSMobileClient.sharedInstance().interceptApplication(application, didFinishLaunchingWithOptions:launchOptions)
}
It actually throws the error before I make any invocation, so I think the lines above may be triggering the problem?
To login, I do the following, in my main viewController:
override func viewDidLoad() {
super.viewDidLoad()
if !AWSSignInManager.sharedInstance().isLoggedIn {
presentAuthUIViewController()
}
else{
getCredentials()
}
...
}
func presentAuthUIViewController() {
let config = AWSAuthUIConfiguration()
config.enableUserPoolsUI = true
config.backgroundColor = UIColor.white
config.logoImage = #imageLiteral(resourceName: "logoQ")
config.isBackgroundColorFullScreen = true
config.canCancel = true
AWSAuthUIViewController.presentViewController(
with: self.navigationController!,
configuration: config, completionHandler: { (provider:
AWSSignInProvider, error: Error?) in
if error == nil {
self.getCredentials()
} else {
// end user faced error while loggin in, take any required action here.
}
})
}
func getCredentials() {
let serviceConfiguration = AWSServiceConfiguration(region: .USEast1, credentialsProvider: nil)
let userPoolConfiguration = AWSCognitoIdentityUserPoolConfiguration(clientId: "id",
clientSecret: "secret",
poolId: "id")
AWSCognitoIdentityUserPool.register(with: serviceConfiguration, userPoolConfiguration: userPoolConfiguration, forKey: "key")
let pool = AWSCognitoIdentityUserPool(forKey: "key")
if let username = pool.currentUser()?.username {
userName = username
}
It loggs in, and I retrieve the user name.
Any tips? I followed some of the instructions in other posts but they didn't work, plus what most disconcerts me is that it was working!
Thanks in advance
I think this means that your refresh token expired.
So, not 100% sure of what was going on, but as I understand it there was a problem with the credentials for the user in the user pool. I reset the password and all started working fine again!
If anyone needs more details just ask, and if anyone understands this better let me know..
In my Xcode Project I already have a sign in feature that uses a user's username and password they created. Now I want to integrate a Facebook login in the project, but I am not completely sure how to do this. When someone makes an account through they way I have it now, they make and save a username and a password which can then be used in with PFUser.logIn(withUsername: ..., password: ...) for whenever they want to sign in again.
But with Facebook, I do not know what unique identifier I am suppose to save their account with. I know there is a Facebook id that I can extract, but how do I login the user in after I get this? Like I said before I currently use PFUser.logIn(withUsername: ..., password: ...) to log the users' in then I just use PFUser.current()?.username to get all data related to that user. I heard that I am suppose to use PFFacebookUtils.logInInBackground for this, but I already tried implementing it but when I press the "Continue with Facebook button", the app crashes (I screenshot error and placed it at bottom). I have copied my code of what I have so far. How do I integrate a signup with Facebook feature that will allow me to save a users Facebook id and what method do I use to sign the user in (i.e. PFFacebookUtils.logInInBackground)? Here's my code so far:
#IBOutlet var facebookSignUpButton: FBSDKLoginButton!
var fullnameFB = String()
var idFB = String()
var emailFB = String()
var isFBSignUp = Bool()
override func viewDidLoad() {
super.viewDidLoad()
signUpWithFacebook()
}
func signUpWithFacebook() {
facebookSignUpButton.readPermissions = ["email", "public_profile"]
facebookSignUpButton.delegate = self
self.view.addSubview(facebookSignUpButton)
}
func loginButton(_ loginButton: FBSDKLoginButton!, didCompleteWith result: FBSDKLoginManagerLoginResult!, error: Error!) {
if error != nil { //if theres an error
print(error)
} else if result.isCancelled { // if user cancels the sign up request
print("user cancelled login")
} else {
PFFacebookUtils.logInInBackground(with: result!.token!) { (user, error) in
if error == nil {
if let user = user {
if user.isNew {
print("User signed up and logged in through Facebook!")
} else {
print("User logged in through Facebook!")
}
if result.grantedPermissions.contains("email") {
if let graphRequest = FBSDKGraphRequest(graphPath: "me", parameters: ["fields": "email, name"]) {
graphRequest.start(completionHandler: { (connection, result, error) in
if error != nil {
print(error?.localizedDescription ?? String())
} else {
if let userDetails = result as? [String: String]{
print(userDetails)
self.fullnameFB = userDetails["name"]!
self.idFB = userDetails["id"]!
self.emailFB = userDetails["email"]!
self.isFBSignUp = true
}
}
})
}
} else {
print("didnt get email")
self.createAlert(title: "Facebook Sign Up", message: "To signup with Facebook, we need your email address")
}
} else {
print("Error while trying to login using Facebook: \(error?.localizedDescription ?? "---")")
}
} else {
print(error?.localizedDescription ?? String())
}
}
}
}
Console output:

As stated in the docs, you need to initialize PFFacebookUtils before using it, like so:
func application(_ application: UIApplication,
didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey : Any]? = nil) -> Bool {
// CODE...
PFFacebookUtils.initializeFacebook(applicationLaunchOptions: launchOptions)
}
Important: Must be done after Parse setup (Parse.initialize...).
I have added the latest Facebook SDK to my XCode 7.1 project written for iOS 9.1. Unfortunately all I know is Swift, not Objective C. Facebook's developer site documentation only has the documentation in Objective C. Every search on Google reveals documentation that is just too old because things have changed so much just in the past 6 months. So I'm kind of lost.
I did all the easy stuff with the plist file.
I was able to use:
import FBSDKCoreKit
import FBSDKLoginKit
I also added:
return FBSDKApplicationDelegate.sharedInstance().application(application, openURL: url, sourceApplication: sourceApplication, annotation: annotation)
and
return FBSDKApplicationDelegate.sharedInstance().application(application, didFinishLaunchingWithOptions: launchOptions)
To my AppDelegate.swift file. This all works and builds successfully. I have the correct frameworks added as well, obviously. Beyond this point I'm at a standstill because I don't know the syntax for adding a login button, for capturing what I assume would be returned json strings with tokens and other profile information I can use to store in the user's account, etc.
You're on the right track.
Have you set up your pList yet?
You're gonna have to add to your VC, add a login button, deal with delegate, and then deal with FB info. Something like (but not exactly) this:
class yourVC: UIViewController, FBSDKLoginButtonDelegate, UITextFieldDelegate
{
var loginView : FBSDKLoginButton = FBSDKLoginButton()
viewDidLoad() {
loginView.frame = CGRectMake(20, 20, theWidth-40, 40)
self.view.addSubview(loginView)
loginView.readPermissions = ["public_profile", "email", "user_friends","user_birthday"]
loginView.delegate = self
}
func loginButton(loginButton: FBSDKLoginButton!, didCompleteWithResult result: FBSDKLoginManagerLoginResult!, error: NSError!) {
if ((error) != nil)
{
//handle error
} else {
returnUserData()
}
}
func returnUserData()
{
let graphRequest : FBSDKGraphRequest = FBSDKGraphRequest(graphPath: "me", parameters: ["fields":"id,interested_in,gender,birthday,email,age_range,name,picture.width(480).height(480)"])
graphRequest.startWithCompletionHandler({ (connection, result, error) -> Void in
if ((error) != nil)
{
// Process error
print("Error: \(error)")
}
else
{
print("fetched user: \(result)")
let id : NSString = result.valueForKey("id") as! String
print("User ID is: \(id)")
//etc...
}
})
}
You're gonna have to play around with the returnData() part to get it right, but this code should get you 90% of the way there.
I've included a wide range of permissions (user age, interested in, etc), but you'll have to configure them yourself. Honestly this part (the hard part) is really similar with it's object C counterpart, which is much better documented. Just download some get projects where it's working, and try to parse them together into something that suits your fancy.
It can be hard to get it all working, but give it a go, and keep at it!
If you want to perform login from Facebook on click of your custom button, this will help:
#IBAction func onClickFacebookButton(sender: UIButton){
let login = FBSDKLoginManager()
login.loginBehavior = FBSDKLoginBehavior.SystemAccount
login.logInWithReadPermissions(["public_profile", "email"], fromViewController: self, handler: {(result, error) in
if error != nil {
print("Error : \(error.description)")
}
else if result.isCancelled {
}
else {
FBSDKGraphRequest(graphPath: "me", parameters: ["fields": "first_name, last_name, picture.type(large), email, name, id, gender"]).startWithCompletionHandler({(connection, result, error) -> Void in
if error != nil{
print("Error : \(error.description)")
}else{
print("userInfo is \(result))")
}
})
}
})
}
I am logging into my app using PFFacebookUtils.logInWithPermissions however, the first time I log in the actual login works fine but I get the FB error code = 2500 An active access token must be used to query information about the current user. This results in any graphRequests failing.
If I then recompile the code to the device this error does not occur and all graphRequests work fine. Why is the app not getting an access token upon the first login? Also, if I completely delete the app from the device and reinstall this whole process starts again (error code = 2500 on first attempt).
Also maybe worth noting, this didn't happen with the previous versions of Parse and FB SDKs. I am just starting to move this app into iOS9 and that's when this problem popped up.
Xcode 7.0.1, Parse SDK v1.8.5, FacebookSDKs-iOS-20150910
I was able to resolve this issue by first calling the FBSDK login method followed by the Parse SDK login method (inside the FBSDK callback):
#IBAction func facebookButtonAction(sender: AnyObject) {
// Ensure that PFUser == nil - just in here because I heard it can help with some possible issues
PFUser.logOut()
let permissions = ["public_profile", "email", "user_friends"]
// First, login with FB’s SDK
let login: FBSDKLoginManager = FBSDKLoginManager()
login.logInWithReadPermissions(permissions, handler: {(result: FBSDKLoginManagerLoginResult!, error: NSError!) in
if (error != nil) {
NSLog("Process error")
} else {
if result.isCancelled {
NSLog("Cancelled")
} else {
NSLog("Logged in")
// Then with Parse’s, upon FB login success
PFFacebookUtils.logInWithPermissions(permissions) { (user, error) -> Void in
if let user = user {
if user.isNew {
print("User signed up and logged in through Facebook!”)
//...
} else {
print("User logged in through Facebook!")
//...
}
} else {
print("Uh oh. The user cancelled the Facebook login.")
//...
}
}
}
}
})
}
