NSData(contentsOfURL: url) always returning nil

I have this code in a new playground

import Foundation

let blogsURL: NSURL = NSURL(fileURLWithPath: "/Users/Francis/Documents/Xcode_projects/KM registratie/blogs.json")
let data = NSData(contentsOfURL: blogsURL)

On the second line the playground tells me that it (correctly) initialised the URL referring to file:///Users/Francis/Documents/Xcode_projects/KM%20registratie/blogs.json and on the third line the playground tells me that data is nil

I already googled around but no question seems to be the exact same problem. I found this "NSData contentsOfURL constructor returns nil", but neither restarting Xcode nor restarting my entire computer fixes the problem.

Solution

  • playgrounds are sandboxed and it seems that there isn't an easy way to reach outside their "box". XML parsing in swift the title of this question is a bit misleading, the answer on it does answer this question
