Integration

The CometChatCalls 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 CometChatCalls 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 CometChatCalls 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.

Note

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 CometChatCalls 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 CometChatCalls 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 'CometChatSDK', '4.0.52'
  pod 'CometChatCallsSDK', '4.0.6'

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 CometChatCallsSDK

CometChatCallsSDK version 4.0.0 is compatible with 4.0.0 version of CometChatSDK

Swift Package Manager

1. Go to your Swift Package Manager's File tab and select Add Packages.

2. Add CometChatProCalls into your Package Repository as below:

Swift

https://github.com/cometchat/ios-calls-sdk.git

3. To add the package, select Version Rules, enter Up to Exact Version, 4.0.4, and click Next.

4. 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 'CometChatCallsSDK', '4.0.0'

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

#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()

Objective C

@interface ViewController : UIViewController

@property (nonatomic, strong) CallSetting *callSettings;
@property (nonatomic, strong) NSString *appId;
@property (nonatomic, strong) NSString *region;
@property (nonatomic, strong) NSString *host;

@end

@implementation ViewController


-(void)setupCallsSetting {

   self.callAppSettings = [[[[[CallAppSettingsBuilder new]
                             setAppId:self.appId]
                             setRegion:self.region]
                            setHost:self.host]
                            build];
}
@end

Note

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))")
}
