# init(column:) Creates a new column of arrays of integers from a given column whose elements can be converted to an array of integers. ``` init(column: MLDataColumn) where T : MLDataValueConvertible ``` ## Parameters `column` An [`MLDataColumn`](/documentation/CreateML/MLDataColumn) of elements convertible to an of . ## Discussion Use this initializer to create a column of arrays of integers from another column. Start by creating a column that is convertible to a column of arrays of integers. Then use [`init(column:)`](/documentation/CreateML/MLDataColumn/init(column:)-2rxtu) to convert the column to a column of arrays of integers. ```swift let intsColumn = MLDataColumn(column: stringsColumn) print(intsColumn) // Prints [1, 2, 3, 4, 5] ``` --- Copyright © 2026 Apple Inc.
