Using the aws-sdk-ios, we are implementing custom auth flow:
http://docs.aws.amazon.com/cognito/latest/developerguide/amazon-cognito-user-pools-authentication-flow.html

However in the iOS sdk, with the method getSession, the isInitialCustomChallenge value is set to NO. How can I get session with the callback of custom challenge?

result.user.getSession(uuidString, password: password, validationData: nil).continueWith(block: {(task:AWSTask) -> Any? in
if let error = task.error as NSError? {
print("Error.. (error)")
}
else if let result = task.result {
print("Result.. (result)")
}
return nil
})

I am not able to the custom challenge callback. The same for android sdk exist: http://docs.aws.amazon.com/cognito/latest/developerguide/using-amazon-cognito-user-identity-pools-android-sdk.html

Many thanks

If you need help with understanding how to implement something in particular then we suggest that you first look into our developer guide. You can also simplify your process of creating an application by using Mobile Hub.

After many trial and error, I have been able to sign in with custom challenge using the sdk. I have documented it here: https://medium.com/@victorleungtw/aws-cognito-user-pools-with-mobile-sdk-for-ios-using-custom-challenge-5d40a06a3b07
