# removeMonitor(_:)

Removes the specified event monitor.

## Declaration

```swift
class func removeMonitor(_ eventMonitor: Any)
```

## Parameters

- `eventMonitor`: The event handler object to remove.

## Discussion

Discussion You must ensure that eventMonitor is removed only once. Removing the same eventMonitor instance multiple times results in an over-release condition, even in a Garbage Collected environment
