# NSComparisonPredicate.Modifier.all

A predicate to compare all entries in the destination of a to-many relationship.

## Declaration

```swift
case all
```

## Discussion

Discussion The left hand side must be a collection. The corresponding predicate compares each value in the left hand side with the right hand side, and returns false when it finds the first mismatch—or true if all match.
