Playgrounds are sandboxed, so you won't be able to just grab files from anywhere in your user folder. Here's how to add that file to your playground to make it accessible:

1. Find your ".playground" file in the Finder
2. Right click and choose "Show Package Contents"
3. You should see "timeline.xctimeline", "contents.xcplayground", and "section-1.swift"
4. Make a new folder called "Resources"
5. Copy "app.xml" into that new folder

Now your file will be available inside the sandbox. You can retrieve it from the bundle and load it into the NSXMLParser like this:

let url: NSURL! = NSBundle.mainBundle().URLForResource("app", withExtension: "xml")
var xml = NSXMLParser(contentsOfURL: url)
