# convert(_:to:)

Converts a point from the view’s coordinate system to that of a given view.

```
func convert(_ point: NSPoint, to view: NSView?) -> NSPoint
```

## Parameters

`point`

A point specifying a location in the coordinate system of the view.

`view`

The view into whose coordinate system `point` is to be converted. Both `view` and the view must belong to the same [`NSWindow`](/documentation/AppKit/NSWindow) object, and that window must not be `nil`. If `view` is `nil`, this method converts to window coordinates instead.

## Return Value

The point converted to the coordinate system of `aView`.

## See Also

[`contentView`](/documentation/AppKit/NSWindow/contentView)

The window’s content view, the highest accessible view object in the window’s view hierarchy.

[`-  ancestorSharedWithView:`](/documentation/AppKit/NSView/ancestorShared(with:))

Returns the closest ancestor shared by the view and another specified view.
