If the singleton object does not exist, the SDK instantiates the default service client with `defaultServiceConfiguration` from `[AWSServiceManager defaultServiceManager]`.

 For example, set the default service configuration in `- application:didFinishLaunchingWithOptions:`
 
 *Swift*

        let credentialProvider = AWSCognitoCredentialsProvider(regionType: .USEast1, identityPoolId: "YourIdentityPoolId")

        AWSServiceManager.default().defaultServiceConfiguration = configuration
 
        return true

 *Objective-C*
