# init(labeledByNamesAt:separator:index:type:continueOnFailure:) Reads training examples from a directory containing files having their labels in the name. The name can contain multiple words separated by a `separator`. So the `index` tells the position of the label in the file name. Files with incorrect name format are ignored. ``` init(labeledByNamesAt url: URL, separator: Character = ".", index: Int = 0, type: UTType, continueOnFailure: Bool = false) throws ``` ## Parameters `url` URL of directory containing the files. `separator` The separator used in the name. Default value is “.” `index` Index of the label in the file name. Default value is 0. `type` Type of files. `continueOnFailure` A Boolean value indicating whether to continue reading files after encountering a file that is not readable. The default value is `false`. ## Discussion Take for example this directory structure: ``` / fold1-foo-file1.png fold1-foo-file2.png fold2-foo-file3.png fold1-bar-file4.png fold1-bar-file5.png fold2-bar-file6.png ``` When we specify separator as “-” and index as 1, it would produce two labels (foo and bar) with three URLs each. --- Copyright © 2026 Apple Inc.
