What is the difference between swarm and whisper in Ethereum?

Could you elaborate on the distinct differences between Swarm and Whisper in the Ethereum ecosystem? I understand both are components of the platform, but I'm curious to know how they differ in terms of their functionalities and applications. Swarm, for instance, seems to be focused on decentralized storage, while Whisper seems to handle secure messaging. However, I'd like to have a deeper understanding of how these two technologies work together or separately within Ethereum, and what specific benefits they each bring to the platform.
