I recently spent some time figuring out the best way to find the URL/paths of the recommended iOS file system used directories.

I felt that iOS URL/paths was very confusing:

  • NSSearchPathForDirectoriesInDomains returns an array of paths
  • FileManager’s urls(for directory: FileManager.SearchPathDirectory, in domainMask: FileManager.SearchPathDomainMask) returns an array of URL
  • NSHomeDirectory() returns 1 String
  • String (ie paths) are missing the URL management methods that NSString had

So I came up with this little FileManager’s extension that could be useful to many:

extension FileManager {
    func homeDirectory() -> URL {
        return URL(fileURLWithPath: NSHomeDirectory())

    func homeDirectoryPath() -> String {
        return NSHomeDirectory()

    func tmpDirectory() -> URL {
        return homeDirectory().appendingPathComponent("tmp")

    // ...
