[swift-users] No prefix habit

[Rod Brown]

The issue here is not so much “banning” as that the reasons for the prefix aren’t relevant in Swift.

In Obj-C, there are no namespaces, so to avoid collisions, frameworks are prefixed with letters to ensure separation. Apple reserved NS, UI and some others for their frameworks and recommended that devs use 3 letter prefixes.

These reasons are not apparent in Swift due to implicit namespacing from modules.

You can feel free to drop prefixes for clarity in Swift.
