# init(column:) Creates a new column of strings from a given column whose elements can be converted to strings. ``` init(column: MLDataColumn) where T : MLDataValueConvertible ``` ## Parameters `column` An [`MLDataColumn`](/documentation/CreateML/MLDataColumn) of elements convertible to . ## Discussion Use this initializer to create a column of strings from another column. Start by creating a column that is convertible to a column of strings. ```swift let doublesColumn = MLDataColumn([1.0, 2.718, 3.14, 4.2, 5.1]) print(doublesColumn) // Prints [1.0, 2.718, 3.14, 4.2, 5.1] ``` Then use [`init(column:)`](/documentation/CreateML/MLDataColumn/init(column:)-ztkv) to convert the column to a column of strings. ```swift let stringsColumn = MLDataColumn(column: doublesColumn) print(stringsColumn) // Prints ["1", "2.718", "3.14", "4.2", "5.1"] ``` --- Copyright © 2026 Apple Inc.
