# hasPermission(_:in:)

Checks the specified permission against the currently granted permissions in a specific tab.

## Declaration

```swift
func hasPermission(_ permission: WKWebExtension.Permission, in tab: (any WKWebExtensionTab)?) -> Bool
```

## Parameters

- `permission`: The permission for which to return the status.
- `tab`: The tab in which to return the permission status, or nil if the tab is not known or the global status is desired.

## Discussion

Discussion Permissions can be granted on a per-tab basis. When the tab is known, permission checks should always use this method.
