The Swift-compatible API tutorials follow a simple container-based object 
lifecycle. The first step requires you to setup a connection between your 
client and the RADOS Gateway server. Then, you may follow a natural 
container and object lifecycle, including adding and retrieving object 
metadata. See example code for the following languages:

- `Java`_
- `Python`_
- `Ruby`_
