The CometChatProCalls is developed to keep developers in mind and aims to reduce development efforts significantly. Let’s start to integrate Calls Kit into your project.

​
Before you begin

Before installing CometChatProCalls for iOS, you need to create a CometChat application on the CometChatPro Dashboard, which comprises everything required in a chat service including users, groups, calls & messages. You will need the App ID , AuthKey, Region of your CometChat application when initializing the SDK. i. Register on CometChat 🧑💻
  • To install CometChatProCalls for iOS, you need to first register on CometChat Dashboard. Click here to sign up.
ii. Get Your Application Keys 🔑
  • Create a new app
  • Head over to the QuickStart or API & Auth Keys section and note the App ID, Auth Key, and Region.
Each CometChat application can be integrated with a single client app. Within the same application, users can communicate with each other across all platforms, whether they are on mobile devices or on the web.

​
Prerequisites

The minimum requirements for CometChatProCalls for iOS are:
  • macOS
  • Xcode
  • iOS 13.0 and later
  • Swift 5.0+

​
Get Started

You can start building a modern calling experience in your app by installing Pluto UIKit. This developer kit is an add-on feature to CometChatPro iOS SDK so installing it will also install the core Chat SDK.

​
Step 1 : Create a project

To get started, open Xcode and create a new project.

​
Enter name, identifier and proceed.

​
Step 2 : Install CometChatProCalls Kit

You can install CometChatProCalls for iOS through Swift Package Manager or Cocoapods

​
CocoaPods

We recommend using CocoaPods, as they are the most advanced way of managing iOS project dependencies. Open a terminal window, move to your project directory, and then create a Podfile by running the following command.
  • Swift
$ pod init
Add the following lines to the Podfile.
  • Swift
platform :ios, '11.0'
use_frameworks!

target 'YourApp' do
  pod 'CometChatPro', '3.0.917
  pod 'CometChatCalls', '3.0.2'
end
And then install the CometChatCalls framework through CocoaPods.
  • Swift
$ pod install
If you’re facing any issues while installing pods then use the below command.
  • Swift
$ pod install --repo-update
Always get the latest version of CometChatCalls by command.
  • Swift
$ pod update CometChatCalls
CometChatCalls version 3.0.0 is compatible with 3.0.914 version of CometChatPro

​
Swift Package Manager

  1. Go to your Swift Package Manager’s File tab and select Add Packages.
  1. Add CometChatProCalls into your Package Repository as below:
  • bash
https://github.com/cometchat-pro/ios-calls-sdk.git
  1. To add the package, select Version Rules, enter Up to Exact Version, 3.0.0, and click Next.
  1. Once, the package is added it will look like this.

​
Cocoa Pods

Go to root directory. (Where the .xcodeproj reside.) and perform these commands.
Pod installation
  1. pod init
  2. open -a Xcode Podfile
Your pod file will open in the text editor. Add your project dependency. 3. pod ‘CometChatProCalls’, ‘3.0.0-alpha7’ 4. For M1 Mac - arch -x86_64 pod install or For Intel Mac - pod install

​
Initialize CometChatProCalls

​
1. CallsAppSettings

The init() method takes CallsAppSettings as a parameter and user can set it by CallsAppSettingBuilder. User should be first set the CallsAppSettings. CallsAppSettings has 3 parameters
  1. appId it is mandatory parameter.
  2. region It is mandatory parameter.
  3. host It is optional parameter.
  • Swift
  • Objective C
#import CometChatProCalls

let appID = "APP_ID"
let region = "REGION"
let host = "HOST"
let callSettings: CometChatProCalls.CallSettings?

let callAppSettings = CallAppSettingsBuilder()
            .setAppId(appId)
            .setRegion(region)
            .setHost(host)
            .build()
Make sure you replace the appId with your CometChat appId and region with your app region in the above code.

​
2. Init() Method

From the above CallAppSettings, pass the settings to the init() method.
  • Swift
guard let callAppSettings = callAppSettings else { return }

CometChatCalls.init(callsAppSettings: callAppSettings) { success in
    print("CometChatCalls init success: \(success)")
} onError: { error in
    print("CometChatCalls init error: \(String(describing: error?.errorDescription))")
}
