AWS iOS SDK, The service configuration is `nil - ios

Question

I need to create a platform endpoint in AWS for SNS push notifications.
In order to register the device to get the push notifications, I need to send the device ID to SNS, Im not using cognito, I want to upload the token using the AWS SDK from the phone:
AWSSNSCreatePlatformEndpointInput
when I try to register with:
- (void)application:(UIApplication*)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData*)deviceToken{
NSLog(#"deviceToken: %#", deviceToken);
/* This is the code to actually register the device with Amazon SNS Mobile Push based on the token received */
NSString * myArn = #"arn:aws:sns:us-east-1:123456789123:app/APNS_SANDBOX/AmazonMobilePushExample";
NSLog( #"Submit the device token [%#] to SNS to receive notifications.", [self deviceTokenAsString:deviceToken] );
AWSSNSCreatePlatformEndpointInput *platformEndpointRequest = [AWSSNSCreatePlatformEndpointInput new];
platformEndpointRequest.customUserData = #"MyUserID;iPhone5";
platformEndpointRequest.token = [self deviceTokenAsString:deviceToken];
platformEndpointRequest.platformApplicationArn = myArn;
//THIS LINE CRASHING
AWSSNS *snsManager = [AWSSNS defaultSNS];
// [snsManager createPlatformEndpoint:platformEndpointRequest];
}
But I get the crash error:
'The service configuration is nil. You need to configure awsconfiguration.json, Info.plist or set defaultServiceConfiguration before using this method.'
So, how to configure either my plist of my method directly with out cognito?
Cheers

What was needed was to set the
AWSServiceManager defaultServiceManager
as Below:
- (void)awsStartWithDeviceToken:(NSData *)deviceToken {
// Set the log level
[AWSLogger defaultLogger].logLevel = AWSLogLevelVerbose;
// Login
AWSStaticCredentialsProvider *credentialsProvider = [[AWSStaticCredentialsProvider alloc]
initWithAccessKey:#"AKIAIxxxYYYA"
secretKey:#"Tx0vhKv1xMaaabbbbccccM5+3R9lEitw2Hzw"];
AWSServiceConfiguration *configuration = [[AWSServiceConfiguration alloc]
initWithRegion:AWSRegionAPSoutheast2
credentialsProvider:credentialsProvider];
[AWSServiceManager defaultServiceManager].defaultServiceConfiguration = configuration;
// Create SNS Client
AWSSNS *snsManager = [AWSSNS defaultSNS];
/* This is the code to actually register the device with Amazon SNS Mobile Push based on the token received. */
AWSSNSCreatePlatformEndpointInput* platformEndpointRequest = [AWSSNSCreatePlatformEndpointInput new];
platformEndpointRequest.customUserData = #"kUniqueID"; // It could be anything.
platformEndpointRequest.token = [self deviceTokenAsString:deviceToken]; // Device Token No for APNS
platformEndpointRequest.platformApplicationArn = #"arn:aws:sns:ap-southeast-2:86434343191:app/APNS_SANDBOX/ios_lambada";
[snsManager createPlatformEndpoint:platformEndpointRequest completionHandler:^(AWSSNSCreateEndpointResponse * _Nullable response, NSError * _Nullable error) {
NSLog(#"errore : %#", error);
}];
}
