# ClassificationDistribution A classification distribution that contains a probability for each classification label. ``` struct ClassificationDistribution where Label : Hashable ``` ## Topics ### Creating the distribution [`init(C)`](/documentation/CreateMLComponents/ClassificationDistribution/init(_:)) Creates a classification distribution. ### Getting the properties [`var endIndex: Int`](/documentation/CreateMLComponents/ClassificationDistribution/endIndex) The index of the final element in the classification distribution. [`var labelsSortedByProbability: [Label]`](/documentation/CreateMLComponents/ClassificationDistribution/labelsSortedByProbability) The labels sorted by decreasing probability. [`var mostLikelyLabel: Label?`](/documentation/CreateMLComponents/ClassificationDistribution/mostLikelyLabel) The label with the highest probability. [`var startIndex: Int`](/documentation/CreateMLComponents/ClassificationDistribution/startIndex) The index of the initial element in the classification distribution. ### Getting the index [`func index(after: Int) -> Int`](/documentation/CreateMLComponents/ClassificationDistribution/index(after:)) Returns the index immediately after an element index. [`func index(before: Int) -> Int`](/documentation/CreateMLComponents/ClassificationDistribution/index(before:)) Returns the index immediately before an element index. ### Labeling and mapping [`func topLabels(Int) -> [Label]`](/documentation/CreateMLComponents/ClassificationDistribution/topLabels(_:)) Computes the most likely labels in the classification set. [`func map((Classification) throws -> Classification) rethrows -> ClassificationDistribution`](/documentation/CreateMLComponents/ClassificationDistribution/map(_:)) Creates a new classification distribution by applying a transformation to every element. ### Accessing by subscript [`subscript(_:)`](/documentation/CreateMLComponents/ClassificationDistribution/subscript(_:)) Accesses a contiguous range of elements. ## Relationships ### Conforms To [`Encodable`](/documentation/Swift/Encodable) [`Equatable`](/documentation/Swift/Equatable) [`Copyable`](/documentation/Swift/Copyable) [`Collection`](/documentation/Swift/Collection) [`Escapable`](/documentation/Swift/Escapable) [`SendableMetatype`](/documentation/Swift/SendableMetatype) [`Decodable`](/documentation/Swift/Decodable) [`Sequence`](/documentation/Swift/Sequence) [`Sendable`](/documentation/Swift/Sendable) [`Hashable`](/documentation/Swift/Hashable) --- Copyright © 2026 Apple Inc.
