ios - I am getting error pathextension is unavailable use pathextension on nsurl insted -

here code

let pathval = exportedfileurl!.path let pathex: string = pathval!.pathextension 

i guess exportedfileurl optional nsurl, according variable name.

according nsurl class reference, path property string, can't use nsurl object , use pathextension property on it.

try instead :

let pathex = exportedfileurl!.pathextension
