7 years ago @Domsware sorry you are having trouble.
I don't know whether your problem is configuration or leaving out a step, but I did a step by step re-production of what you are trying to do and here are the steps. I tried them twice! They work.
- First: I assume what you are trying to do is to make one of the MySampleApp's from Mobile Hub work with Cognito User Pools. And that you have set up a user pool and also have configured the app for google and facebook and your desired capabilities in the mobile hub.
- assuming that is correct, and done then here are the steps
(There might be easier processes than the one above to do all this, but this way you can use the symbolic debugger on the AWS code (which I find is necessary from time to time.))
- Configure and download the sample app
- Build the sample app and it should run, if it doesn’t, fix that first.
- Create an AWSKeys.xcconfig file, with the key information from your Info.plist in your MySampleApp project.
- Open your “MySampleApp” in xcode
- Rename your Info.plist to OldInfo.plist( Under App/SupportingFiles )
- Right Click on SupportingFiles and choose add files to “MySampleApp”
- Add the file Info.plist from SignIn-awsmhh (If you don’t have it, grab that off github… Suggest you github clone —recursive the repo)
- (This part is variable depending upon what DEMO features you enabled in the Mobile Hub site, but in Info.plist copy any of the keys under AWS in the OldInfo.plist into you Info.plist. This includes ContentManager, DynamoDBObjectMapper, Cognito, and UserFileManager.
- BUT do not change IdentityManager or CredentialsProvider
- delete OldInfo.plist move to trash
- Right Click on MySampleApp and choose add files to “MySampleApp”
- Add the .gitignore file from SignIn-awsmhh (you will have to hold Command-Shift-. to see it and add it once you choose add files)
- In your project settings -> Select Project -> Select Info -> Select Configurations -> Select the AWSKeys.xcconfig file in both Debug and Release.
- (now your keys configuration comes from the AWSKeys.xcconfig file.)
- IMPORTANT: Choose product clean (this will rebuild the Info.plist from the AWSKeys.xcconfig
- at this point, the app should run just fine just like it used to. Try it to be sure. If it doesn’t fix that first.
- Now you are going to replace the aws-mobile-hub-helper-framework, with the updated one.
- Under Frameworks delete AWSMobileHubHelper.framework and move it to trash
- Then in terminal:
- (to the app home (cd MySampleApp (where the .xcodeproj file is) - Now we will put MySampleApp under git source control
git init
Add all the files to it (.gitignore file will make it omit your AWSKeys.xcconfig)
git add -A
git submodule add https://github.com/BruceBuckland/aws-mobilehub-helper-ios.git
cd aws-mobilehub-helper-ios
Now you have to get to the old Swift 2 version of the AWSCUPIdPSignInProvider.swift file. Because the swift3 version is not compatible with the Mobile Hub.
git checkout 79b396ca7c4718bac263d6c1604de96d15b67bf3
You can also use any commit before swift3 compatibility. This is only because the Mobile Hub downloads swift 2 code still
pod install
(gets the requirements for the aws-mobile-hub-helper-ios)
- open aws-mobile-hub-helper-ios in xcode (open ./aws-mobile-hub-helper-ios/AWSMobileHubHelper.xcworkspace)
- Click run to Build the project
- back in the terminal the following line will build the .framework (the script will run for a minute and put out BUILD SUCCEEDED)
./Scripts/GenerateHelperFramework.sh
cd ..
pod init
- edit the Podfile using your favorite editor and make the Podfile look like this.
platform :ios, '9.0'
target 'MySampleApp' do
# Comment this line if you're not using Swift and don't want to use dynamic frameworks
use_frameworks!
# Pods for MySampleApp
pod 'AWSCognito'
pod 'AWSCognitoIdentityProvider'
end- Get dependencies
pod install
- open xcode and open the xcworkspace for MySampleApp (NOT the xcodeproj)
- right click on Frameworks and add files to MySampleApp
- the file you want is in aws-mobile-hub-helper-ios/builtFramework/framework and then highlight AWSMobileHubHelper.framework and click Add.
- Build and run the project.
- Now the app should work and function fine, if it doesn’t, stop and fix it.
- You are using the updated version of the aws-mobile-hub-helper-ios, and you can now (for instance) click cancel in facebook login without a problem… which the standard app does not do). You can also add UserPools to your login providers.
- To add userpools
- In your app edit MySampleApp/MySampleApp/App/SignIn/SignInViewController.swift. Replace the function handleCustomLogin() with
// CUPIdP changes
// Now facebook and Google prompt for UID password, but in the demo app this signin view
// prompts BEFORE the user even chooses the signInProvider.
// For a "minimal change" fix, just to get User Pools working for the first time
// I am going to stick the username and password into the shared
// instance of AWSCUPIdPSignInProvider.
// If AWS had thought harder about AWSIdentityManager it would have a loginWithUsernamePassword
// method.
func handleCustomLogin() {
// Handle Login logic for User Pools Sign In using OpenID Connect
//
// let AWSInfoIdentityManager = "IdentityManager"
if (customUserIdField.text != nil) && (customPasswordField.text != nil) {
let customSignInProvider = AWSCUPIdPSignInProvider.sharedInstance
// Push userId and password to our AWSCUPIdPSignInProvider
customSignInProvider.customUserIdField = customUserIdField.text
customSignInProvider.customPasswordField = customPasswordField.text
handleLoginWithSignInProvider(customSignInProvider)
}
}
- This code references AWSCUPIdPSignInProvider, a new AWSSignInProvider, it is not in the framework (because AWS still distributes the framework as a static library, and because swift files can't make static libraries) ,
- Right click MySampleApp (the source directory not the one at the top level) and Add files to MySampleApp
- add the file you will find in the MySampleApp/aws-mobile-hub-helper-ios/AWSMobileHubHelper/SignIn/AWSCUPIdPSignInProvider.swift.
- Build and run.
- You can now log in with Cognito User Pools, Facebook and Google.
- Further (if you change the MainViewController.swift a little so that you can signin even when you are signed in… ) you can log into multiple ID providers simultaneously and merge cognito identities between the providers.
I know this just lets you login (the signup etc won’t work. You can use SignIn-awsmhh to create accounts). If you want to create accounts, update attributes, etc in the sample there is a little work to do, but not too much. If you can’t figure out how, you will have to take a look at the SignIn-awsmhh example.

After spending some time studying this project, I want to integrate it in my own project. Hélas, without success.
What I have done
Replaced
AWSMobileHubHelper.frameworkandViewController.swiftobtained at AWS Mobile console by SignIn-awsmhh's.Problem
App crashed after few seconds with following error:
*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[__NSDictionaryM removeObjectForKey:]: key cannot be nil'This seems to be related to Identity Pool Configuration as stated by the log:
AWSKeys.xcconfigis the same as in the SignIn-awsmhh project.
