Cannot get AWSS3PutObjectRequest in v2 AWS SDK to duplicate S3PutObjectRequest in v1 SDK

Question

Having problems with the new Amazon SDK, https://github.com/aws/aws-sdk-ios-v2

I'm just trying to write a file to an s3 bucket that already exists. Here's the code that I can't get to work for some reason (even though it logs "success").

AWSStaticCredentialsProvider *credentialsProvider = [AWSStaticCredentialsProvider credentialsWithAccessKey:@"KEY" secretKey:@"SECRET_KEY"];
AWSServiceConfiguration *configuration = [AWSServiceConfiguration configurationWithRegion:AWSRegionUSEast1 credentialsProvider:credentialsProvider];
[AWSServiceManager defaultServiceManager].defaultServiceConfiguration = configuration;

AWSS3 *s3 = [[AWSS3 alloc] initWithConfiguration:configuration];

AWSS3PutObjectRequest *logFile = [AWSS3PutObjectRequest alloc];
logFile.bucket = @"test";
logFile.key = @"file2";
logFile.contentType = @"text/plain";
logFile.body = @"this is a test";
[[s3 putObject:logFile] continueWithBlock:^id(BFTask *task) {
    NSLog(@"Totally did it");
    return nil;
}];

The prior SDK (v1.x) this worked, but I'm trying to switch over because I like Bolts framework functionality.

AmazonS3Client *s3 = [[AmazonS3Client alloc] initWithAccessKey:@"KEY" withSecretKey:@"SECRET_KEY"];
S3PutObjectRequest *logFile = [[S3PutObjectRequest alloc] initWithKey:@"file1" inBucket:@"test"];
logFile.contentType = @"text/plain";
    NSString* myStuff = @"this is a test";
NSData* log = [myStuff dataUsingEncoding:NSUTF8StringEncoding];
logFile.data = log;
[s3 putObject:logFile];

Anyone out there playing with the new SDK who can tell me what I'm doing wrong here?

UPDATE - New Code Snippet

 AWSStaticCredentialsProvider *credentialsProvider = [AWSStaticCredentialsProvider credentialsWithAccessKey:awsAccessKey secretKey:awsSecretKey];
AWSServiceConfiguration *configuration = [AWSServiceConfiguration configurationWithRegion:AWSRegionUSEast1 credentialsProvider:credentialsProvider];
[AWSServiceManager defaultServiceManager].defaultServiceConfiguration = configuration;

/* This section works but posts as text/xml
AWSS3TransferManager *transferManager = [AWSS3TransferManager defaultS3TransferManager];
AWSS3TransferManagerUploadRequest *getLog = [AWSS3TransferManagerUploadRequest new];
*/
AWSS3 *transferManager = [[AWSS3 alloc] initWithConfiguration:configuration];
AWSS3PutObjectRequest *getLog = [AWSS3PutObjectRequest alloc];
getLog.bucket = awsS3Bucket;
getLog.key = awsS3FileNameString;
getLog.contentType = @"text/plain";
NSString *documentsDirectory = [NSSearchPathForDirectoriesInDomains (NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0];
NSString *fileName = [documentsDirectory stringByAppendingPathComponent:logFileName];
long long fileSize = [[[NSFileManager defaultManager] attributesOfItemAtPath:fileName error:nil][NSFileSize] longLongValue];
getLog.body = [NSURL fileURLWithPath:fileName];
getLog.contentLength = [NSNumber numberWithUnsignedLongLong:fileSize];

/* 
[[transferManager upload:getLog] continueWithBlock:^id(BFTask *task) {
*/

[[transferManager putObject:getLog] continueWithBlock:^id(BFTask *task) {        
    if(task.error)
    {
        NSLog(@"Error: %@",task.error);
    }
    else
    {
        NSLog(@"Got here: %@", task.result);

    }
    return nil;
}];

Thanks again.

The body property of AWSS3PutObjectRequest needs to be either NSURL or NSData. If you convert the NSString to NSData like you are doing in v1 code snippet, it should work.
