# add(_:)

Adds a URL to the post.

## Declaration

```swift
func add(_ url: URL!) -> Bool
```

## Parameters

- `url`: The URL to add to the post.

## Return Value

Return Value Returns a Boolean value that indicates whether the URL was successfully added.

## Discussion

Discussion This method returns false if url does not fit in the currently available character space or if the view controller has already been presented to the user (and therefore cannot be changed). Character limits are dependent on the target service and are documented by the service provider. For links to documentation for the supported services, see Table 1 in SLRequest.
