Let's integrate our SDK in few minutes

Quick Start#

Chat SDKs for iOS#

With CONTUS MirrorFly Chat SDK for iOS, you can easily add real-time chat features to your client app within 30 minutes.

Through our client SDK, you can initialize and configure chat into your app with minimal efforts.

Note : If you're looking for the fastest way to build your app’s UI with MirrorFly Chat SDKs, you can use our sample apps. To get our sample apps, click here

Getting Started#


The below are the requirements for chat SDK for iOS,

  • Xcode 14.1 or later
  • iOS 12.1 or later
  • Swift 5.0 or later

Things To Be Noted Before You Get Started#

SDK License Key#

To integrate MirrorFly Chat SDK into your app, you will need a SDK License Key. The MirrorFly server will use this license key to authenticate the SDK in your application.

To get the License Key,#

Step 1: Register here to get a MirrorFly User account. Registration is subject to verification and would take up to 24 hours.

Step 2: Login to your Account

Step 3: Get the License key from the application Info’ section

Step 4: Download the iOS SDK


Integrate the Chat SDK#

Step 1: Add the following ChatSDK pod to your Podfile. If pod hasn't been initialised yet means, create a Podfile by executing pod init command.

pod 'MirrorFlySDK', '5.17.1'

Step 2: Add the below given pod hook code block at the end of the pod file and thus, finally install the pods by executing pod install command.

post_install do |installer|
installer.pods_project.targets.each do |target|
target.build_configurations.each do |config|
config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = '12.1'
config.build_settings['ENABLE_BITCODE'] = 'NO'
config.build_settings['APPLICATION_EXTENSION_API_ONLY'] = 'No'
config.build_settings['EXCLUDED_ARCHS[sdk=iphonesimulators*]'] = 'arm64'
config.build_settings['BUILD_LIBRARY_FOR_DISTRIBUTION'] = 'YES'

Step 3 : Now, disable the bitcode for your project

Goto Project -> Build Settings -> Filter the term `Bitcode` -> and select No from the dropdown


Configure the SDK server & Data#

Now, configure the server details in SDK and access the data globally using the AppDelegate class.

You can copy the license key from the 'Overview’ section in the Console dashboard.

let LICENSE_KEY = "xxxxxxxxxxxxxxxxxxxxxx"

Initialize ChatSDK#

Add the following import statement below before accessing SDK anywhere in your project.

import MirrorFlySDK

To start using the sdk, there are a few basic pieces of data that must be made available for the SDKs to function perfectly.

Thus, we utilize the usage of the initializeSDK function to validate the license key and to fetch critical data from server for SDK initialization. Furthermore, in your project you must use the AppDelegate class within the didFinishLaunchingWithOptions method call the initialization method by passing the license key. Let's have a look at the example given below.

    ChatManager.initializeSDK(licenseKey: LICENSE_KEY) { isSuccess, flyError, flyData in }


    LICENSE_KEYStringUsed to proceed with Registration
    CALLBACKFlyCompletionHandlerFlyCompletionHandler is implemented and expressed as lambda expression


    The below method should be called to register a new user. This method will take care of both Sandbox mode registration as well as Live mode registration .


    Unless you logged out of a session, make sure that you have called the Registration method only once in an application

    Note: While registration, the below registerApiService method will accept the additional params required for notification processing on server and IS_FORCE_REGISTER as an optional param for maintaining sessions, USER_TYPE as an optional param to provide type of user and META_DATA as an optional param to provide MetaData of user.

      try! ChatManager.registerApiService(for: USER_IDENTIFIER ) { isSuccess, flyError, flyData in
      var data = flyData
      if isSuccess {
      // This is your Username
      guard let username = data["username"] as? String else{
      // This is your JID
      // Ex. 12345678@xmpp-preprod-sandbox.mirrorfly.com (USER_IDENTIFIER+@+domain of the chat server)
      guard let userJid = data["userJid"] as? String else{
      let error = data.getMessage()
      print("#chatSDK \(error)")
      USER_IDENTIFIERStringUnique Id to Register the User. User identifiers can only contain lowercase alphanumeric characters, hyphens (-), and underscores (_).)
      APNS_DEVICE_TOKENStringToken to register APNS device (optional)
      VOIP_DEVICE_TOKENStringToken to register VoIP device (optional)
      IS_EXPORTBooltrue for production(apns certificate) builds and false for sandbox(apns certificate)builds
      IS_FORCE_REGISTERBooldefault value true provide true to force the logout of the old session If the registered user has reached the maximum no of multi-sessions or provide false to allow registration till the maximum no of multi-sessions
      USER_TYPEStringType of the user (optional)
      META_DATA[MetaData]list of key - value pair of metadata object. Maximum size is 3 (optional)
      CALLBACKFlyCompletionHandlerFlyCompletionHandler is implemented and expressed as lambda expression

      To know more about FlyCompletionHandler click here


      If IS_FORCE_REGISTER is false, and it reached the maximum no of multi-sessions then registration will not succeed it will throw a 405 exception, Either IS_FORCE_REGISTER should be true or one of the existing session need to be logged out to continue registration.

      Note: If you want to use your own Id, you can use the userJid in the Register response.


      Save your own contact details in DB after registration. Your contact detail will be used while sending group messages. Call below method to save your own contact details,

      let userProfile: ProfileDetails = ContactManager.shared.saveTempContact(userId: "OUR OWN JID" , name: "OUR NAME")

      To generate a unique user id, you must pass the username in the method let userJID: String = try FlyUtils.getJid(USERNAME)

      Connect to the Chat Server#

      Once Registration was successful, ChatSDK automatically attempts to connect to the Chat Server and ChatSDK also observe the changes in application state, and accordingly it will try to connect and disconnect the Chat Server.

      Observe Connection Events#

      The connection status can be observed and tracked by confirming the ConnectionEventDelegate. To do that you need to set ‘delegate’ in your ViewController's viewDidAppear method like below.

        ChatManager.shared.connectionDelegate = self

        Once the ConnectionEventDelegate has been set, you will be able to receive the connection status in the delegate method as mentioned below.

          func onConnected() {
          // Navigate to Conversation screen

          To know more about ConnectionEventDelegate visit ConnectionEvent Delegate

          Preparing user jid#

          To generate a JID for any user, use the below method.

            try? FlyUtils.getJid(USER_NAME)
            USER_NAMEStringunique username which we get from Register response.

            Send a One-to-One Message#

            The below method is used to send a text message from one user to another.

              var textMessage = TextMessage()
              textMessage.toId = TO_JID
              textMessage.messageText = TEXT
              FlyMessenger.sendTextMessage(messageParams: textMessage) { isSuccess, error, chatMessage in
              if isSuccess {
              // Update the UI
              // Handle the error
              TO_JIDStringJID of the end user
              TEXTStringIndicates the text message that needs to be sent
              CALLBACKFlySendMessageListenercallback to observe the action status

              Receive a One-to-One Message#

              Set the delegate in your ViewController's viewDidAppear method using below syntax and confirm the MessageEventsDelegate class, this will enable you to see other incoming messages and related events.

                ChatManager.shared.messageEventsDelegate = self

                Once the delegate has been set, we will be able to receive the incoming message in the method mentioned below.To know more about other methods in MessageEventsDelegate.

                  func onMessageReceived(message: ChatMessage, chatJid: String) {
                  // Message received from chatJid, content is message.messageTextContent

                  Note: MessageEventsDelegate protocol has 12 delegate methods onMessageReceived is one of them. Kindly visit MessageEvent Delegate to know more about them.
