contentsOfDirectoryAtPath returns items in a different order

hi,

i ran into a variation of this problem a while ago, and i specifically noted for myself the need to sort the urls (thinking that the problem came from compiling on different machines):

if var availableURLs = myBundle.urls(forResourcesWithExtension: "json", subdirectory: "Session Formats JSON") {
  // sort required -- turns out that compiling on a different machine might
  // not put the JSON files in alphabetical order
  availableURLs.sort() { $0.path < $1.path }

i know you're using contentsOfDirectoryAtPath, but i just checked its documentation, under the Discussion section: "The order of the files in the returned array is undefined."

(so i did the right thing, but probably for the wrong reason.)

hope that helps,

DMG
