There are some similar question however none of those solve my problem.
Using Xcode 11.1
MacOS Cataline 10.15
I clone this "active-directory-b2c-ios-swift-native-msal" and try to run getting Error "Could not acquire token: Error Domain=MSALErrorDomain Code=-50000 "(null)" UserInfo={MSALErrorDescriptionKey=Failed to start an interactive session, MSALInternalErrorCodeKey=-42008, MSALCorrelationIDKey=C9207A45-6A7D-416B-90E4-93E08F28A637}"
After changing B2C details same issue getting .
Please let me know what is issue, Is this issue for Xcode/OS/MSAL version or some issue with Code??

I am using the swift package AWSiOSSDKV2 from https://github.com/aws-amplify/aws-sdk-ios-spm
I can log in using the SDK but how can I use refresh Token to generate new accessToken using their SDK?
func login() {
let pool = AWSCognitoIdentityUserPool(forKey: PortalUserConfig.POOL_NAME)
if let user = pool?.getUser() {
user.getSession(username, password: password, validationData: nil).continueWith(block: { task -> Any? in
if let error = task.error {
let errorMessage = (error as NSError).userInfo["message"] as? String
} else {
guard let accessToken = task.result?.accessToken else {
return nil
}
print(accessToken)
let refreshToken = task.result?.refreshToken
print(refreshToken)
}
return nil
})
}
}
The Amplify library will automatically fetch new id and access tokens if they have expired and the refresh token is still valid. You can adjust the lifetime of your refresh tokens in the settings for your User Pool client. To learn more about OAuth token lifetime strategies, you can read up on the options over at OAuth.com.
I implemented a social network app that uses Cognito for refreshing token. But still, I can't get my new tokens. When I first log-in to my server and get my first ID and token from it, The token expires after a while and I can't get any token. This is my implementation:
class DeveloperAuthenticatedIdentityProvider : AWSCognitoCredentialsProviderHelper {
override func token() -> AWSTask<NSString> {
self.identityId = ProfileDAL.shared.getId()
return AWSTask(result: NSString(string: ProfileDAL.shared.getToken()))
}
override func logins() -> AWSTask<NSDictionary> {
return super.logins()
}
}
I put this lines in my viewDidLoad right after getting first token from my server
let devAuth = DeveloperAuthenticatedIdentityProvider(regionType: MY_REGION, identityPoolId: MY_IDENTITY_POOL_ID, useEnhancedFlow: true, identityProviderManager:nil)
let credentialsProvider = AWSCognitoCredentialsProvider(regionType: MY_REGION, identityProvider:devAuth)
let configuration = AWSServiceConfiguration(region: MY_REGION, credentialsProvider:credentialsProvider)
AWSServiceManager.default().defaultServiceConfiguration = configuration
and right after them, I use bellow lines to get my tokens:
AWSMobileClient.default().getTokens { (tokens, error) in
if let error = error {
print("Error getting token \(error.localizedDescription)")
} else if let tokens = tokens {
print(tokens.accessToken!.tokenString!)
}
}
finally I can't get my new tokens and it gives me this error:
AWSMobileClientError
▿ notSignedIn : 1 element
- message : "User is not signed in, please sign in to use this API."
Sorry, my subject isn't very specific.
I'm dealing with managing multiple users in my realm and having some problems. I have a user register with their email and name, then when realm logs in and creates a SyncUser, I create a new YpbUser object with the email, name, and SyncUser.current.identity in YpbUser.id.
When a user logs in, I want to use their email to look up whether there's an existing YpbUser for their email. I'm doing it this way so in the future if someone uses username/password and then uses Google auth (not yet implemented), those SyncUsers can get to the same YpbUser.
Below is my code for checking for an existing YpbUser, along with my realm setup code. The problem I'm having is that it usually, but not always, fails to find a YpbUser even if that user exists (I'm looking at the YpbUser list in realm studio and the user with that email is definitely there!)
Inspecting from within existingUser(for:in:), users is usually 0, but it sometimes non-zero.
I assume the issue lies somewhere in the fact that I'm pretty much just guessing on how to use SyncSubscription.observe.
Please help?
fileprivate func openRealmWithUser(user: SyncUser) {
DispatchQueue.main.async { [weak self] in
let config = user.configuration(realmURL: RealmConstants.realmURL, fullSynchronization: false, enableSSLValidation: true, urlPrefix: nil)
self?.realm = try! Realm(configuration: config)
let songSub = self?.realm?.objects(Song.self).subscribe()
let usersSub = self?.realm?.objects(YpbUser.self).subscribe()
self?.usersToken = usersSub?.observe(\.state, options: .initial) { state in
if !(self?.proposedUser.email.isEmpty)! {
self?.findYpbUser(in: (self?.realm)!)
}
}
self?.performSegue(withIdentifier: Storyboard.LoginToNewRequestSegue, sender: nil)
}
}

if proposedUser != YpbUser() { // self.proposedUser.email gets set from the login method
let existingUser = YpbUser.existingUser(for: proposedUser, in: realm)
guard existingUser == nil else { // If we find the YpbUser, set as current:
try! realm.write {
pr("YpbUser found: \(existingUser!)")
YpbUser.current = existingUser }
return
}

Q & A Style: See Answer Below
How Can I get the username from a user logged in with Cognito?
I've done this and my user is logged in, now what?
AWSAuthUIViewController.presentViewController(
with: self.navigationController!,
configuration: config, completionHandler: { (provider: AWSSignInProvider, error: Error?) in
if error == nil {
//get parameters
}
} else {
print(error as Any)
}
})
}
Prerequisites:
App registered with MobileHub
Cognito Setup in MobileHub
Mobilehub integrated with Swift Project using AWS SDK
If you're like me, you did this with little to no difficulty and now you're stuck trying to get the username and other parameters from the logged in user. There are a lot of answers, but thus far, I haven't stumbled upon one that gets you all the way there.
I was able to piece this together from various sources:
func getUsername() {
//to check if user is logged in with Cognito... not sure if this is necessary
let identityManager = AWSIdentityManager.default()
let identityProvider = identityManager.credentialsProvider.identityProvider.identityProviderName
if identityProvider == "cognito-identity.amazonaws.com" {
print("************LOGGED IN WITH COGNITO************")
let serviceConfiguration = AWSServiceConfiguration(region: .USWest2, credentialsProvider: nil)
let userPoolConfiguration = AWSCognitoIdentityUserPoolConfiguration(clientId: "YourClientID", clientSecret: "YourSecretKey", poolId: "YourPoolID")
AWSCognitoIdentityUserPool.register(with: serviceConfiguration, userPoolConfiguration: userPoolConfiguration, forKey: "YourPoolName (typically formatted as YourAppName_userpoool_MOBILEHUB_12345678")
let pool = AWSCognitoIdentityUserPool(forKey: "YourPoolName")
// the following line doesn't seem to be necessary and isn't used so I've commented it out, but it is included in official documentation
// let credentialsProvider = AWSCognitoCredentialsProvider(regionType: .USWest2, identityPoolId: "YourPoolID", identityProviderManager:pool)
if let username = pool.currentUser()?.username {
print("Username Retrieved Successfully: \(username)")
} else {
print("Error getting username from current user - attempt to get user")
let user = pool.getUser()
let username = user.username
print("Username: \(username)")
}
}
}
To get your ClientID, Secret Key, and PoolID, check your awsconfiguration.json
To get your PoolName, login to MobileHub, and in your project's backend, go to User Sign in, click Email and Password, then click Edit in Cognito. The following page will have your Pool Name as "YourAppName_userpool_MOBILEHUB_12345678"
Edit: To get all of the attributes as well:
if let userFromPool = pool.currentUser() {
userFromPool.getDetails().continueOnSuccessWith(block: { (task) -> Any? in
DispatchQueue.main.async {
if let error = task.error as NSError? {
print("Error getting user attributes from Cognito: \(error)")
} else {
let response = task.result
if let userAttributes = response?.userAttributes {
print("user attributes found: \(userAttributes)")
for attribute in userAttributes {
if attribute.name == "email" {
if let email = attribute.value {
print("User Email: \(email)")
}
}
}
If you're using Cognito User Pools, you can use this:
import AWSUserPoolsSignIn
AWSCognitoUserPoolsSignInProvider.sharedInstance()
.getUserPool()
.currentUser()?
.username
I have the structure set up for updating user attributes, in this case the preferred username to use as an alias for signing in.
var attributes = [AWSCognitoIdentityUserAttributeType]()
let prefUsername = AWSCognitoIdentityUserAttributeType();
prefUsername?.name = "preferred_username";
prefUsername?.value = usernameField.text!;
attributes.append(prefUsername!);
let attributesRequest = AWSCognitoIdentityProviderUpdateUserAttributesRequest();
attributesRequest.userAttributes = attributes;
idProvider?.updateUserAttributes(attributesRequest)
Only thing I have no idea how to do is get the access token. I've looked in as much documentation as I could think of but I had no luck finding place to get access token.
You can use the api to initiate auth and get an AccessToken from the AuthenticationResult.
https://docs.aws.amazon.com/cognito-user-identity-pools/latest/APIReference/API_InitiateAuth.html
/// Function to retreive the current token for the logged in user.
///
/// - Parameter completion: A completion block with an error or the token. Called back on the main thread.
public func getJWT(completion: #escaping((_ error: Error?, _ token: AWSCognitoIdentityUserSessionToken?) -> Void)) {
guard let user = self.pool.currentUser() else {
let nsError = NSError(domain: "JWT Error", code: 500, userInfo: ["message": "No Logged in user"])
completion(nsError, nil)
return
}
user.getSession().continueWith { (task) -> Any? in
DispatchQueue.main.async {
if let error = task.error {
completion(error, nil)
}else if let token = task.result?.idToken {
completion(nil, token)
}else {
completion(nil, nil)
}
}
}
}
Where self.pool is the AWSCognitoIdentityUserPool you hopefully set up correctly.
You would have to authenticate first to establish a session with Cognito User Pools. That session would contain an access token which you can then pass to every subsequent request. I see you are using the low level SDK methods. Here is a sample in swift for SignIn:
https://github.com/awslabs/aws-sdk-ios-samples/tree/master/CognitoYourUserPools-Sample/Swift
