The AWS Mobile Hub simplifies the process of building, testing, and monitoring mobile applications that make use of one or more AWS services. It helps you skip the heavy lifting of integrating and configuring services by letting you add and configure features to your apps, including user authentication, data storage, backend logic, push notifications, content delivery, and analytics—all from a single, integrated console.

This helper code is the source for the AWSMobileHubHelper.framework file which is included with every Objective C and Swift application download from AWS Mobile Hub.

You can download the framework along with the sample app from the mobile hub console under the build section. The framework is currently distributed as a static library.

You can build the framework from source using the Script. The API reference documentation can be generated using the Script.

At this time we are accepting pull requests only for Bug fixes (one bug fix per requests). For new features please submit feedback on the mobile hub console (link for feedback on the bottom left corner). Please make sure that your pull requests comply with the license.

##Modifications, Fixes, Enhancements For this fork:

authenticatedBy method A user readable name (providerKey) of the currentSignInProvider, such as Facebook or Google or Cognito Your User Pools. Note you may be authenticated with more id's logins may contain multiple providers, but only one is the currentSignInProvider Returns providerKey of currentSignInProvider or "Guest"

currentSignInProvider property Some processes in a mobile app require access to the currentSignInProvider. For example with custom OpenIdConnect or CognitoUserPools providers you may need to have access to the provider in order to sign-up a user, or recall a forgotten password. The SignInProvider class is a good place to encapsulate interfacing with the authentication provider, but we need to be able to get the currentSignInProvider

activeProviders property Returns an array of instances of AWSSignInProviders with active sessions. SignIn Providers that have active sessions store a value in NSUserDefaults with thier providerKey as a key. Usually this value is "YES", but does not need to be (some have stored a token). The existence of any value is enough to indicate that there is an active session with this provider. Returns NSArray of active AWSSignInProvider instances

providerKey method A user readable name of the signInProvider passed as an such as Facebook or Google or Cognito Your User Pools. This is the value for the Class name key in the Info.plist ClassNameKeyDictionary Returns provider name or nil (if classname not found)

interceptApplication method Modified so that it re-instantiates any AWSSignInProviders listed in the SignInProviderKeyDictionary in Info.plist Some (Cognito User Pools, or developer providers) will interact directly with the application. Modified so that it re-instantiates any AWSSignInProviders listed in the SignInProviderKeyDictionary in Info.plist (not just Google and Facebook).

Other: Support for Allow Simultaneous Active Accounts in Info.plist Requires Allow Identity Merging to be YES.

Support for Allow Identity Merging in Info.plist Various modifications to functions including logins to produce a merged logins response when a user logs in to a second account while using a first account. Controlled by the Info.plist boolean flag “Allow Identity Merging”. This allows the credentials provider to merge identityId’s when two logins occur simultaneously.

###Edge Case Bugs

Facebook:

Sign-In, choose Facebook or Google, then choose "Done". AWSIdentityProvider shows authenticated by, and is listed in active providers and has a user name, but does NOT show logged in.
Sign-In, choose Facebook, then choose "Cancel". Same as above Sign-In, choose Google, then choose "Deny". Same as above

Sign-In, type the wrong password on Cognito Your User Pools, get the error, say ok, and Shows Authenticated by CUP but shows Bruce Buckland as provider (in nslog) but shows Sign On Error not properly reversed (strange difference)
