AppIntentError`](/documentation/AppIntents/IntentParameterContext/needsDisambiguationError(among:dialog:)) Returns a `restartPerform` error with context for the user to disambiguate amongst an array of values from for this parameter and re-perform the intent with the new value. [`func needsValueError(IntentDialog?) -> AppIntentError`](/documentation/AppIntents/IntentParameterContext/needsValueError(_:)) Returns a `restartPerform` error with context to request a value from the user for this parameter and re-perform the intent with the new value. [`func requestConfirmation(for: Value.ValueType, dialog: IntentDialog?) async throws -> Bool`](/documentation/AppIntents/IntentParameterContext/requestConfirmation(for:dialog:)) Use `requestConfirmation` when you need to the ask user to confirm the parameter value. [`func requestConfirmation(for: Value.ValueType, dialog: IntentDialog?, view: ViewType) async throws -> Bool`](/documentation/AppIntents/IntentParameterContext/requestConfirmation(for:dialog:view:)-6n0qp) Use `requestConfirmation` when you need to the ask user to confirm the parameter value. [`func requestConfirmation(for: Value.ValueType, dialog: IntentDialog?, view: () -> ViewType) async throws -> Bool`](/documentation/AppIntents/IntentParameterContext/requestConfirmation(for:dialog:view:)-97i0g) Use `requestConfirmation` when you need to the ask user to confirm the parameter value. [`func requestDisambiguation(among: [Value.ValueType], dialog: IntentDialog?) async throws -> Value.ValueType`](/documentation/AppIntents/IntentParameterContext/requestDisambiguation(among:dialog:)) Request that the user disambiguate amongst an array of values for this parameter. [`func requestValue(IntentDialog?) async throws -> Value.ValueType`](/documentation/AppIntents/IntentParameterContext/requestValue(_:)) Request a value from the user for this parameter. ## Relationships ### Conforms To [`SendableMetatype`](/documentation/Swift/SendableMetatype) [`AnyIntentValue`](/documentation/AppIntents/AnyIntentValue) [`Sendable`](/documentation/Swift/Sendable) --- Copyright © 2026 Apple Inc.
