# isRequired

Whether the assessment requires this executable. Defaults to NO.

## Declaration

```swift
var isRequired: Bool { get set }
```

## Discussion

Discussion Governs what happens when the executable cannot be enforced — for example, when signature validation fails under allowsOnlyParticipantsToRun. A non-required participant is silently dropped; a required one prevents the session from beginning. note: requiresSignatureValidation.
