# add(_:)

Adds the specified selection to the receiving selection.

## Declaration

```swift
func add(_ selection: PDFSelection)
```

## Discussion

Discussion Selections do not have to be contiguous. If the selection to be added overlaps with the receiving selection, the overlap is removed in a process called normalization.
