# Session

A session type that the handler serves.

## Declaration

associatedtype Session : AccessoryFeatureSession
```

## Discussion

Discussion This associated type conforms to AccessoryFeatureSession, and each feature pins it through that feature’s own Handler type alias, such as AccessoryWorker.Handler.
