# truePositiveCount(of:)

Returns the number of times the predicted label matched the true label.

## Declaration

```swift
func truePositiveCount(of label: Label) -> Int
```

## Parameters

- `label`: The label to use as true positive.

## Return Value

Return Value The true positive count.

## Discussion

Discussion If the label does not have a confidence threshold, the true positive count is number of elements in the ground truth labels collection that contains the label. If the label has a confidence threshold NaN, the true positive count is 0. If the label is not in the known set of labels, the true positive count is 0.
