# NSApplication.TerminateReply.terminateLater

## Declaration

```swift
case terminateLater
```

## Discussion

Discussion It may be OK to proceed with termination later. Returning this value causes Cocoa to run the run loop in the NSModalPanelRunLoopMode until your app subsequently calls reply(toApplicationShouldTerminate:) with the value true or false. This return value is for delegates that need to provide document modal alerts (sheets) in order to decide whether to quit.
