# activate(from:options:)

Attempts to activate the application using the specified options.

## Declaration

```swift
func activate(from application: NSRunningApplication, options: NSApplication.ActivationOptions = []) -> Bool
```

## Parameters

- `application`: The application to activate.
- `options`: The options to use during activation.

## Return Value

Return Value Returns true if the request is allowed by the system, otherwise false.

## Discussion

Discussion Use this method to request app activation. Calling this method doesn’t guarantee app activation. For cooperative activation, the other application should call yieldActivation(to:) or equivalent prior to the target application invoking activate().
