Get filename without extension

get-filename-without-extension.swift

// https://hashaam.com/2017/09/02/get-filename-without-extension

let path = "hls_a128_v4.m3u8"
let url = URL(string: path)
let filename = url?.deletingPathExtension().lastPathComponent

print(filename) // hls_a128_v4

let fileExtension = url?.pathExtension

print(fileExtension) // m3u8

This fails if the filename contains spaces
