n completing the steps instructed, you will now have a completely built iOS chat app for Ecommerce that is similar to the below screenshot:

Prerequisites

To create an ecommerce app in iOS using swift, you will need, you will need 

• Development Environment: Xcode 13+
• Programming Language: Swift 5.0+
• Platform: iOS 13+
• In App SDKs: MirrorFly Video SDKs

Note: If you’d like to build the swift ecommerce chat on our sample app, you can check out our GitHub repositories.

Steps to integrate MirrorFly chat SDKs for e-commerce apps in iOS with Swift

Step 1: Create a New Xcode Project

• Launch Xcode on your device
• Create a new project or open an existing project
• From the Template grids, choose SingleView App

• A form page will open. Fill in all the required fields and configure your project. 

Step 2: Get the MirrorFly License Key

A license key is needed for the server to authenticate your SDK. To acquire one, you’ll need an account with MirrorFly

• Signup with MirrorFly and complete the account setup process
• After verification, log in to your MirrorFly Account
• From the Account Overview page, download the iOS SDK file

Step 3: MirrorFly SDK Integration

1. Add the following ChatSDK pod to your Podfile. If the pod hasn’t been initialized yet, create a Podfile by executing the pod init command.

pod 'MirrorFlySDK', '5.12.0'

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

3. Now, disable the bitcode for your project

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

4. Initiate and add the pod hook block at the end of the pod file as mentioned below. And then, continue to install the pods.

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['BUILD_LIBRARY_FOR_DISTRIBUTION'] = 'YES'
    end
  end
end

5.  Configure The Capabilities For Your E-commerce Chat App 

• Go to Project
• Click on Target  
• Choose Signing & Capabilities
• Click ‘+’ at the top left corner 
• Search for the capabilities: App groups and Background Mode
• Right under Background Mode, you need to enable the below capabilities:
  • Audio, Airplay, and Picture in Picture
  • Remote notifications
  • Background fetch

Step 4: Configure the MirrorFly SDK Server & Data 

• In this step, you need to add the details including the License key (downloaded in Step 1), and configure the server. This action will take you a step closer to adding chat functionality for user messaging in your ecommerce app. 
• Add the necessary server information to the AppDelegate class.

let LICENSE_KEY = "xxxxxxxxxxxxxxxxxxxxxx"

Step 5: Initialization of Chat SDK

• Provide the basic data needed to build the messaging SDK

• Further, use the AppDelegate class within the didFinishLaunchingWithOptions method.

ChatSDK.Builder.setAppGroupContainerID(containerID: CONTAINER_ID)

      .setLicenseKey(key: LICENSE_KEY)
      .isTrialLicense(isTrial: true)
      .setDomainBaseUrl(baseUrl: BASE_URL)
      .buildAndInitialize()

Step 6: User Registration

To register a user in the sandbox mode or in the live mode, use the below method in the ChatSDK.Builder class

try! ChatManager.registerApiService(for:  USER_IDENTIFIER ) { isSuccess, flyError, flyData in
        var data = flyData
        if isSuccess {
         // This is your Password
           guard let password = data["password"] as? String else{
               return
           }
           // This is your Username
           guard let username = data["username"] as? String else{
               return
           }
        }else{
            let error = data.getMessage()
            print("#chatSDK \(error)")
        }
    }

Step 7: Connect the Chat SDK to the MirrorFly Server

A server connection is needed to send or receive messages within your Ecommerce Chat App. To establish the connection, use the below method:

ChatManager.connect()

Step 8: Disconnect the Chat Server

To disconnect the connection between the chat server and the SDK, you need to call the below method:

ChatManager.disconnect()

Step 9: Add One-to-One Chat 

Send one-to-one Chat:

You need to use the below method to send one-to-one messages:

FlyMessenger.sendTextMessage(TO_JID, TEXT) { isSuccess,error,chatMessage in
     if isSuccess {
        // Update the UI
     }else{
        // Handle the error
     }
 }

Receive One-to-one Messages

To see other incoming messages, you need to set the delegate in your ViewController’s viewDidAppear method and confirm the MessageEventsDelegate class.

  ChatManager.shared.messageEventsDelegate = self

After setting up the delegate, you will start receiving incoming messages from other SDK users.

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

Step 10: Add Group Chat Feature For Messaging On Your E-commerce Chat App

You can create groups for the stakeholders in your business to drive more engagement and transactions. The following steps will guide you through. 

Prepare the Group Chat jid

To prepare the group JID. FlyUtils.getGroupJid(groupId : String), the SDK provides the below utility method.

FlyUtils.getGroupJid(groupId : String)

Group Creation

In order to create a group, you need to call the below method

GroupManager.shared.createGroup(groupName: "ABCXYZ", participantJidList: [jids], groupImageFileUrl: "", completionHandler: { [self] isSuccess, flyError, flyData in

        // Update the UI
    } else{
        // failure case of the group creation
    }
})

Create the Group Profile

From the server or local, you need to get a group profile using the below method.

GroupManager.shared.getGroupProfile(groupJid: groupId, fetchFromServer: fromServer, completionHandler: { isSuccess, flyError, flyData in
    if isSuccess {
        let data =  (flyData.getData() as?
        ProfileDetails)
        // Update the UI
    } else{
        // failure case of get group profile

        // failure cases
    }
}

Call the below method to add or update the group image

GroupManager.shared.updateGroupProfileImage(groupJid: groupId, groupProfileImageUrl: selectPath, completionHandler: { isSuccess, flyError, flyData in
    if isSuccess {
       // Update UI
    } else{
       // failure case
    }
})
