# becomeActive()

Tells a context to become the active context.

## Declaration

```swift
func becomeActive()
```

## Mentioned in

Informing ClassKit that a task is about to begin

## Discussion

Discussion You activate contexts to inform ClassKit which tasks are most recently or commonly visited. Only one context can be active at a time, so if you tell a context to become active when another already is, the framework automatically deactivates the old one.
