# changeCount

The receiver’s change count.

## Declaration

```swift
var changeCount: Int { get }
```

## Discussion

Discussion The change count starts at zero when a client creates the receiver and becomes the first owner. The change count subsequently increments each time the pasteboard ownership changes. The change count is also returned from clearContents() and declareTypes(_:owner:). You can therefore record the value of changeCount at the time that you take ownership of the pasteboard and compare it with a later value to determine whether you still have ownership.
