# init(_:) Creates a new column from a given sequence of machine learning data values. ``` init(_ source: S) where S : Sequence, S.Element == MLDataValue ``` ## Parameters `source` A sequence of data value daelements for the new column. ## Discussion Use this initializer to create a column from a sequence of data values. ```swift let dataValueOf2 = MLDataValue.int(2) let dataValueOf3 = MLDataValue.int(3) let dataValueOf5 = MLDataValue.int(5) let dataValueOf7 = MLDataValue.int(7) let dataValueOf11 = MLDataValue.int(11) let sequence = [dataValueOf2, dataValueOf3, dataValueOf5, dataValueOf7, dataValueOf11 ] let sequenceColumn = MLUntypedColumn(sequence) print(sequenceColumn) /* Prints... ValueType: Int Values: [2, 3, 5, 7, 11] */ ``` --- Copyright © 2026 Apple Inc.
