Find an 8 letter string of characters that contains only letters from acdegilmnoprstuw such that the hash(the_string) is 25180466553932 if hash is defined by the following pseudo-code:

Int64 hash (String s) {
  Int64 h = 7   
  String letters = "acdegilmnoprstuw"     
  for(Int32 i = 0; i < s.length; i++) {
      h = (h * 37 + letters.indexOf(s[i]))     
  }
  return h

/*
  This example shows how to use getDistributionStatus method in the TestFairy SDK.
  getDistributionStatus queries the server about the app version currently running on device, and checks
  to see if "Distribution" is set to "Enabled" in Build Settings page. 
  The example below will close the app if the distribution was disabled. If there is a newer version of
  this app uploaded to TestFairy, and it is set to "Distribution" => "Enabled", then the code will open a url to
  the new version, offloading to the operating system to install the app.

XState for Swift

This is a rough implementation of the javascript XState library by davidkpiano.

I was looking around for a finite state machine for Swift, and decided to port over the javascript library.

It's not as flexible as the javascript library, but does have that Swift type safety-ness.
