# DataFrame.Row A single row within a data frame. ``` struct Row ``` ## Topics ### Inspecting a row [`var count: Int`](/documentation/TabularData/DataFrame/Row/count) The number of columns in the row. [`let index: Int`](/documentation/TabularData/DataFrame/Row/index) The row’s index in the underlying data frame. [`var base: DataFrame`](/documentation/TabularData/DataFrame/Row/base) The row’s underlying data frame. ### Accessing elements [`subscript(Int) -> Any?`](/documentation/TabularData/DataFrame/Row/subscript(_:)-5tsj0) Accesses a value at a column index. [`subscript(String) -> Any?`](/documentation/TabularData/DataFrame/Row/subscript(_:)-2v7qz) Accesses a value in the row you select by a column name. [`subscript(String, T.Type) -> T?`](/documentation/TabularData/DataFrame/Row/subscript(_:_:)-7gpc3) Accesses a value in the row you select by a column name and type. [`subscript(ColumnID) -> T?`](/documentation/TabularData/DataFrame/Row/subscript(_:)-9o424) Accesses a value in the row you select by a column identifier. [`subscript(Int, T.Type) -> T?`](/documentation/TabularData/DataFrame/Row/subscript(_:_:)-1o38p) Accesses a value in the row you select by a column index and type. ### Describing a row [`var description: String`](/documentation/TabularData/DataFrame/Row/description) A text representation of the row. [`var debugDescription: String`](/documentation/TabularData/DataFrame/Row/debugDescription) A text representation of the row suitable for debugging. [`var customMirror: Mirror`](/documentation/TabularData/DataFrame/Row/customMirror) A mirror that reflects the row. [`func description(options: FormattingOptions) -> String`](/documentation/TabularData/DataFrame/Row/description(options:)) A text representation of the row. ### Comparing two rows [`static func == (DataFrame.Row, DataFrame.Row) -> Bool`](/documentation/TabularData/DataFrame/Row/==(_:_:)) Returns a Boolean that indicates whether the rows are equal. ### Hashing a row [`func hash(into: inout Hasher)`](/documentation/TabularData/DataFrame/Row/hash(into:)) Hashes the essential components of the row by feeding them into a hasher. ### Retrieving an index [`var startIndex: Int`](/documentation/TabularData/DataFrame/Row/startIndex) The index of the initial column in the row. [`var endIndex: Int`](/documentation/TabularData/DataFrame/Row/endIndex) The index of the final column in the row. [`func index(before: Int) -> Int`](/documentation/TabularData/DataFrame/Row/index(before:)) Returns the column index immediately after a column index in the row. [`func index(after: Int) -> Int`](/documentation/TabularData/DataFrame/Row/index(after:)) Returns the column index immediately before a column index in the row. ### Default Implementations [Collection Implementations](/documentation/TabularData/DataFrame/Row/Collection-Implementations) [CustomDebugStringConvertible Implementations](/documentation/TabularData/DataFrame/Row/CustomDebugStringConvertible-Implementations) [CustomReflectable Implementations](/documentation/TabularData/DataFrame/Row/CustomReflectable-Implementations) [CustomStringConvertible Implementations](/documentation/TabularData/DataFrame/Row/CustomStringConvertible-Implementations) [Equatable Implementations](/documentation/TabularData/DataFrame/Row/Equatable-Implementations) [Hashable Implementations](/documentation/TabularData/DataFrame/Row/Hashable-Implementations) [RandomAccessCollection Implementations](/documentation/TabularData/DataFrame/Row/RandomAccessCollection-Implementations) ## Relationships ### Conforms To [`RandomAccessCollection`](/documentation/Swift/RandomAccessCollection) [`Collection`](/documentation/Swift/Collection) [`Equatable`](/documentation/Swift/Equatable) [`CustomDebugStringConvertible`](/documentation/Swift/CustomDebugStringConvertible) [`Escapable`](/documentation/Swift/Escapable) [`Sequence`](/documentation/Swift/Sequence) [`Hashable`](/documentation/Swift/Hashable) [`BidirectionalCollection`](/documentation/Swift/BidirectionalCollection) [`MutableCollection`](/documentation/Swift/MutableCollection) [`Copyable`](/documentation/Swift/Copyable) [`CustomStringConvertible`](/documentation/Swift/CustomStringConvertible) [`CustomReflectable`](/documentation/Swift/CustomReflectable) --- Copyright © 2026 Apple Inc.
