To initialize the SDK, you need to add SinchChatSDK.shared.initialize() to the application function definition in the AppDelegate file. For example:
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
SinchChatSDK.shared.initialize()
return true
}After initializing, you must [set the identity]((/docs/sinch-chat/getting-started/ios/set-identity/).
