ios - Change URL last component name and add extension to the renamed one -


i have following url

file:///users/ivancantarino/library/developer/coresimulator/devices/cce2fca5-05f0-4bb7-9a25-cbc168398a62/data/containers/data/application/e48179f9-84fb-4cb3-b993-1e33fcfb5083/library/caches/cloudkit/34af81edf8344be1cf473ef394e06ccc8e1bc8cf/assets/ae86e028-e4e0-45d5-b5fe-bae975d07f2a.0166f7df06d2562d8d53e70a3779a46de3769584c3

i'm trying rename last part component of url, still having url not filename.

i've managed access last part following code:

func extractandbreakfilenameincomponents(fileurl: nsurl) {       let fileurlparts = fileurl.path!.components(separatedby: "/")     let filename = fileurlparts.last     print("filename:", filename)     // prints: ae86e028-e4e0-45d5-b5fe-bae975d07f2a.0166f7df06d2562d8d53e70a3779a46de3769584c3 }

i want change filename myfile.pdf keeping url

it simple url rename, not creating new one, changing existing one

what's best approach on this?

thank you

you can way

var url = url.init(string: "http://www.example.com/test123")  url?.deletelastpathcomponent() url?.appendpathcomponent("file.pdf")   print(url)

output :http://www.example.com/file.pdf

hope helps you

edit

you need rename file use following code

1) create copy , update last component 

var urlnew = url.init(string: "http://www.example.com/test123")  urlnew?.deletelastpathcomponent() urlnew?.appendpathcomponent("file.pdf")                  {                     try filemanager.default.moveitem(atpath: oldurl!, topath: urlnew)                 } catch {                  }
