# isIndeterminate

A Boolean value that indicates whether the tracked progress is indeterminate.

## Declaration

```swift
var isIndeterminate: Bool { get }
```

## Discussion

Discussion Use isIndeterminate progress only when you’re unable to determine a reasonable value for either completedUnitCount or totalUnitCount. Progress is indeterminate when the value of the totalUnitCount or completedUnitCount is less than zero or if both values are zero. When progress is indeterminate, fractionCompleted returns 0.0 and isFinished returns false. By default, Progress is KVO-compliant for this property. It sends notifications on the same thread that updates the property. The following code snippet clarifies the behavior for setting both totalUnitCount and completedUnitCount to 0. let progress = Progress(totalUnitCount: 0)  progress.completedUnitCount = 0 // default  print("totalUnitCount: (progress.totalUnitCount)")  print("completedUnitCount: (progress.completedUnitCount)")  print("isIndeterminate: (progress.isIndeterminate)")  print("fractionCompleted: (progress.fractionCompleted)")  print("isFinished: (progress.isFinished)") /* Code Output: totalUnitCount: 0 completedUnitCount: 0 isIndeterminate: true fractionCompleted: 0.0 isFinished: false */
