Fixing the "pathExtension is unavailable" error in Swift 2.0

[kjmcneish]

In Swift 2.0, the pathExtension property has been removed from the String class. You can use NSURL's pathExtension instead, but if you want to keep this property on the String class, just use this extension:

Code: [Select]

var pathExtension: String {
       
   get {
      return (self as NSString).pathExtension
   }
}

All the best!
