How can I read a text file in the Resources directory using Swift 3 Playground?

Question

I have a text file I created in the Resources directory of my Swift playground. I am trying to get the directory location of the "Resources" in the Playground during runtime, but it returns some other location that does not even exist.

import PlaygroundSupport
let dirLog = PlaygroundSupport.playgroundSharedDataDirectory

dirLog displays as:

file:///Users/ronaldo/Documents/Shared%20Playground%20Data/

It seems that PlaygroundSupport does not have the methods I need to get this directory location. I saw some mention in another SE question and they used NSBundle class to get the files in Resources. But I can not find ANY NSBundle object to be used in Swift 3.

Each Playground has its own Resources folder, and the actual path is hidden.

In Swift 3, you can get the files in the Resources folder by using Bundle:

let url = Bundle.main.url(forResource: "file", withExtension: "txt")

The path of this Bundle URL contains the path to the current Resources folder.

You can also avoid using Bundle and drag & drop the file from the Resources folder to the Playground itself, creating a file literal.

For example, type let url = and drop the file, from the Resources folder, into the Playground just after the = sign.
