AWS iOS SDK, конфигурация сервиса равна `nil

Что требовалось, так это установить

AWSServiceManager defaultServiceManager

как показано ниже:

- (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);
}];

}
