How to get the filename from the given file path string?

For example if I have a filepath string as

file:///Users/DeveloperTeam/Library/Developer/CoreSimulator/Devices/F33222DF-D8F0-448B-A127-C5B03C64D0DC/data/Containers/Data/Application/5D0A6264-6007-4E69-A63B-D77868EA1807/tmp/trim.D152E6EA-D19D-4E3F-8110-6EACB2833CE3.MOV
and I would like to get the return result as
trim.D152E6EA-D19D-4E3F-8110-6EACB2833CE3.MOV
                maybe you should highlight in Swift that this works only for NSString, like:  var theFileName: NSString = string.lastPathComponent // or var theFileName: String = (string as NSString).lastPathComponent

                in Swift, local filenames are highly suggested to be managed as URLs, not as Strings or NSStrings

                Note that this requires Foundation to be imported. Not a big deal for iOS/Mac apps, but a big deal for Linux/Windows ones.

SWIFT 3.x or SWIFT 4:
Shortest and cleanest way of doing this is below. In this example url variable is type of URL in this way we can have a human readable String result of the full file name with extension like My file name.txt and Not like My%20file%20name.txt
// Result like: My file name.txt
let fileName = url.lastPathComponent
If you want to get the current file name such as for logging purposes, I use this.
Swift 4
URL(fileURLWithPath: #file).lastPathComponent
                Good to know: use init(fileURLWithPath path: __shared String, isDirectory: Bool) to avoid an extra file system access. From the docs: This function avoids an extra file system access to check if the file URL is a directory. You should use it if you know the answer already.

                This is the method the compiler says to use if you call lastPathComponent on a swift String (as opposed to casting to NSString).

let theURL = URL(string: "yourURL/somePDF.pdf")  //use your URL
let fileNameWithExt = theURL?.lastPathComponent //somePDF.pdf
let fileNameLessExt = theURL?.deletingPathExtension().lastPathComponent //somePDF
In order for this to work your url must be of type URL not a string so don't convert it to a string before hand.
You can copy and paste this code directly into playground to see how it works. 
let filename: String = "your file name"
let pathExtention = filename.pathExtension
let pathPrefix = filename.stringByDeletingPathExtension
Updated : 
extension String {
    var fileURL: URL {
        return URL(fileURLWithPath: self)
    var pathExtension: String {
        return fileURL.pathExtension
    var lastPathComponent: String {
        return fileURL.lastPathComponent
Hope it helps.
Below code is working for me in Swift 4.X
 let filename = (self.pdfURL as NSString).lastPathComponent  // pdfURL is your file url
 let fileExtention = (filename as NSString).pathExtension  // get your file extension
 let pathPrefix = (filename as NSString).deletingPathExtension   // File name without extension
 self.lblFileName.text = pathPrefix  // Print name on Label
You can pass the url in fileUrl, like I did below:-
let fileUrl: String = "https://www.himgs.com/imagenes/hello/social/hello-fb-logo.png" // Pass the URL 
let lastPathComponent = URL.init(string: fileUrl)?.lastPathComponent ?? "" // With this you will get last path component
let fileNameWithExtension = lastPathComponent
//This last path component will provide you file Name with extension. 
                This is a little-appreciated code-only answer. Please add some explanation. That will improve your chances for upvotes and also helps fighting the misconception that you can get programming work done here free of charge.

I've done some performance tests (iOS 14, real device, release configuration):
(#file as NSString).lastPathComponent // The fastest option.
URL(string: #file)!.lastPathComponent // 2.5 times slower than NSString.
#file.components(separatedBy: "/").last! // 7 times slower than NSString.
Bonus:
URL(fileURLWithPath: #file, isDirectory: false).lastPathComponent // About the same as URL(string:).
URL(fileURLWithPath: #file).lastPathComponent // 2.5 times slower than with explicit isDirectory.
                While (#file as NSString) is the fastest, you'll get escaped stuff like %20 in the result, which is resolved in the URL(string: #file) case.

To retrieve filename without its extension from a URL in Swift >= 4.2:
let urlWithoutFileExtension: URL =  originalFileUrl.deletingPathExtension()
let fileNameWithoutExtension: String = urlWithoutFileExtension.lastPathComponent
Creates unique "file name" form url including two previous folders
func createFileNameFromURL (colorUrl: URL) -> String {
var arrayFolders = colorUrl.pathComponents
// -3 because last element from url is "file name" and 2 previous are folders on server
let indx = arrayFolders.count - 3
var fileName = ""
switch indx{
case 0...:
    fileName = arrayFolders[indx] + arrayFolders[indx+1] + arrayFolders[indx+2]
case -1:
    fileName = arrayFolders[indx+1] + arrayFolders[indx+2]
case -2:
    fileName = arrayFolders[indx+2]
default:
    break
 return fileName
