New Features

Change Description
Amazon DynamoDB: Unicode Support

The AWS SDK for iOS now properly handles unicode characters within Amazon DynamoDB.

Proper multi-threaded support for synchronous requests.

The AWS SDK for iOS now runs in its own Run Loop Mode to better support synchronous requests run in background threads.
We strongly recommend not making synchronous requests to AWS on the main thread.

Amazon S3 over 3G

Uploading large objects to Amazon S3 using 3G can fail frequently. Upgrading your iOS device to v4.3 helps reduce the failure rate. We are actively working with Apple to find a resolution to this problem.

Users may also refer to the following Article as a work around to uploading larger files over 3G.

Amazon S3 client does not work around known Amazon S3 issues. The Amazon S3 library does not currently work around two known issues with the Amazon S3 API:
  • Bucket names can include '+' symbols in the name, but the '+' symbol does not get replaced in URL encodings and can result in spaces in bucket names instead.
  • It is possible to create an object with a key which includes characters that are not valid XML characters, which will cause an error in the response to the AmazonS3Client listObjects method. Refer to for guidelines on Amazon S3 keys.
