# runLoopModesForAnimating

An array of strings representing the run loop modes in which the animation can run.

## Declaration

```swift
var runLoopModesForAnimating: [RunLoop.Mode]? { get }
```

## Discussion

Discussion The default value of this property is nil, which indicates that the animation can be run in the default, modal, or event-tracking modes. The value of this property is ignored if the animation blocking mode is something other than NSAnimation.BlockingMode.nonblocking. For information about run loop modes and for constants, see RunLoop.
