fileName
The name of the source file.
Declaration
var fileName: String { get }Discussion
The name of the source file is derived from this instance’s fileID property. It consists of the substring of the file ID after the last forward-slash character ("/".) For example, if the value of this instance’s fileID property is "FoodTruck/WheelTests.swift", the file name is "WheelTests.swift".
The structure of file IDs is described in the documentation for #fileID in the Swift standard library.
