Circuit iOS SDK


Welcome to the Circuit iOS SDK. You can use the provided SDK to build a text or media mobile application for iOS.



Get the WebRTC dependency (Source/libCKTNavigator.a) via:

curl -X GET -o "Source/libCKTNavigator.a" ""

CircuitSDK is available through CocoaPods.

You can easily try our sample app by running the following command in your terminal window:

pod try CircuitSDK

To use it simply add the following line to your Podfile:

pod 'CircuitSDK'


You can find the sample application in the iOS Sample App directory. If you try to run the application, you won’t be able to logon. You must add your client id and client secret and install pods. In the terminal navigate to the CircuitKit folder and run the following command:

pod install

This will install the pods and create a CircuitKit.xcworkspace, open that file instaead of the CircuitKit.xcodeproj. In the Sample/Resources folder open AppDelegate.swift, here you can add your client id and client secret. Press the run button


If you do not have any client credentials first sign up for a developer account here

Once your account is approved navigate to Circuit App Registration and follow the instructions to obtain the credentials

Once you receive them you are ready to run the sample application and create your own.

Here are some snippets to get you started.


It's a good idea to initialize the SDK when the application launches, this can be done in the AppDelegate file.

Application scope should be a comma delimited string that can contain any of the following


We use a framework called AppAuth to help with OAuth 2.0 authentication.

AppAuth takes your client id and client secret and returns to you an access token, you can the use this access token to logon.

See AppAuth-iOS for examples using AppAuth

Remember to set your redirectURI you created when registering your application, this redirectURI tells AppAuth how to get back to your application after authentication has completed.

[client initializeSDK:@"ADD CLIENT_ID"
                    oAuthClientSecret:@"ADD CLIENT SECRET"
                    oAuthScope:@"ADD OAUTH SCOPE"];
CKTClient().initializeSDK("ADD CLIENT ID",
                            oAuthClientSecret:"ADD CLIENT SECRET",
                            oAuthScope:"ADD OAUTH SCOPE")

Event Handling

Event handling is already setup in the SDK. All you have to do to provide event handling to your application is add some observers where you want to listen to specific events.

Event Type Description
CKTNotificationBasicSearchResults string Asynchronous search results for startUserSearch or startBasicSearch
CKTNotificationCallEnded string Fired when a call is terminated.
CKTNotificationCallIncoming string Fired when an incoming call is received.
CKTNotificationCallStatus string Fired when the call state, or any other call attribute of a local or remote call changes.
CKTNotificationConnectionStateChanged string Fired when the connection state changes.
CKTNotificationConversationCreated string Fired when a new conversation is created for this user. This can be a brand new conversation, or being added to a conversation.
CKTNotificationConversationUpdated string Fired when an existing conversation is updated.
CKTNotificationItemAdded string Fired when a new conversation item is received. Note that the sender of an item will also receive this event.
CKTNotificationItemUpdated string Fired when an existing conversation item is updated.
CKTNotificationReconnectFailed string Fired when automatic reconnecting to the server fails.
CKTNotificationRenewToken string Fired when token has been renewed after session expiry. Error included on failure.
CKTNotificationSessionExpires string Fired when session expires.
CKTNotificationUserPresenceChanged string Fired when the presence of a subscribed user changes.
CKTNotificationUserSettingsChanged string Fired when one or more user settings for the logged on user change.
CKTNotificationUserUpdated string Fired when the local user is updated.

Adding Observers

[[NSNotificationCenter defaultCenter] addObserver:self
                                        name:CKTNotificationItemAdded object:nil];
                            name:CKTNotificationItemAdded, object: nil)

To listen for events you need to add observers to your application logic. You do this using Apple's Notification Center if you have never used NSNotificationCenter you can find more information on it here

In the example we are watching for an event called CKTNotificationItemAdded which when triggered will fire a method called itemAddedToConversation
