A better way (or at least an alternative in Swift 2.0) is to use the String pathComponents property. This splits the pathname into an array of strings. e.g

if let pathComponents = filePath.pathComponents {
    if let last = pathComponents.last {
        print(" The last component is \(last)") // This would be the extension
        // Getting the last but one component is a bit harder
        // Note the edge case of a string with no delimiters!
    }
}
// Otherwise you're out of luck, this wasn't a path name!
