How to check if Swift URL is directory

How can I check if a Swift URL represents a file or a directory?

There is a hasDirectoryPath attribute on the URL object, but there doesn't seem to be any 'intelligence' behind it. It just reflects the isDirectory value passed to the URL.

code:

  let URL1 = URL(fileURLWithPath: FileManager.default.currentDirectoryPath)
  print(URL1.hasDirectoryPath)
  let URL2 = URL(fileURLWithPath: FileManager.default.currentDirectoryPath, isDirectory: true)
  print(URL2.hasDirectoryPath)

output:

  false
  true
Solution

  • The name says it all "hasDirectoryPath". It doesn't state that the URL is a directory and it exists. It says that it has a directory path. To make sure that the URL is a directory you can get URL ResourceKey isDirectoryKey:

    extension URL {
    var isDirectory: Bool {
       (try? resourceValues(forKeys: [.isDirectoryKey]))?.isDirectory == true
    }
}
