# iterative

An effect that momentarily enables each layer of a symbol-based image in sequence.

```
var iterative: VariableColorSymbolEffect { get }
```

## Discussion

This effect enables each successive variable layer for a short period of time, and then disables the layer until the animation cycle ends. This effect cancels the [`cumulative`](/documentation/Symbols/VariableColorSymbolEffect/cumulative) variant.
