# ApplyRandomly Randomly applies the transformer with the given probability. ``` struct ApplyRandomly where RandomTransformer : RandomTransformer, RandomTransformer.Input == RandomTransformer.Output ``` ## Topics ### Creating an augmentation [`init(probability: Double, () -> RandomTransformer)`](/documentation/CreateMLComponents/ApplyRandomly/init(probability:_:)) Creates an apply randomly augmentation. ### Getting the probability [`let probability: Double`](/documentation/CreateMLComponents/ApplyRandomly/probability) The probability of applying the transformer. Default value is 0.5. ### Applying transformers [`func applied(to: RandomTransformer.Input, generator: inout some RandomNumberGenerator, eventHandler: EventHandler?) async throws -> RandomTransformer.Output`](/documentation/CreateMLComponents/ApplyRandomly/applied(to:generator:eventHandler:)) Randomly applies a transformer on an input. ## Relationships ### Conforms To [`SendableMetatype`](/documentation/Swift/SendableMetatype) [`Sendable`](/documentation/Swift/Sendable) [`RandomTransformer`](/documentation/CreateMLComponents/RandomTransformer) --- Copyright © 2026 Apple Inc.
