# remove(_:)

Removes an observer from the payment queue.

```
func remove(_ observer: any SKPaymentTransactionObserver)
```

## Parameters

`observer`

The observer to remove.

## Discussion

If there are no observers attached to the queue, the payment queue does not synchronize its list of pending transactions with the Apple App Store, because there is no observer to respond to updated transactions.

## See Also

[`transactions`](/documentation/StoreKit/SKPaymentQueue/transactions)

Returns an array of pending transactions.
