Connection Kit
The framework is extremely useful. I had done some research on what our options were for Sandvox when we started developing it, and there aren’t many alternatives, if any. One of the best things about this is that the different connection methods share a common interface, so whether you are uploading to SFTP or just exporting to the file system, you use the same code to accomplish it. It also has operations like delete remote file that you can’t find if you used Apple’s APIs.
