find the parent directory of a file in swift

To find the parent directory of a file in Swift, we can use the URL and FileManager classes provided by the Foundation framework. Here's a sample code snippet:

main.swift
let fileURL = URL(fileURLWithPath: "/path/to/file.txt")
let parentDirectory = fileURL.deletingLastPathComponent()

print("Parent directory: \(parentDirectory.path)")
166 chars
5 lines

In this code, we first create a URL object representing the file's path. Then, we use the deletingLastPathComponent() method to get a new URL object representing the parent directory. Finally, we print the path of the parent directory using the path property.

Note that this code assumes that the file path is valid and that the file exists. You may want to add error handling code to handle cases where these assumptions don't hold.
