Simple snippet to load JSON into from a filepath or URL

    do {
      // Create a string out of the file contents
      let contents = try String(contentsOf: fileURL) // use contentsOfFile for strings
      // Turn it into data to feed JSONSerialization class
      let data     = contents.data(using: String.Encoding.utf8)
      // Attempt to turn it into JSON, or show error
