Hello dear. I hope you are doing well. I’m Yurii a software engineer and ios developer. for rendering the browser we will use a web view, the web has an instance to define the the web link. for the downloading, we will make a http request and call it. before calling the request we will make a loder, any loader can help, let’s say Rapple progress loader to show the user the percentage. then, after completion, we will hide the loader. Plus, for saving files to user, i will use File manger to make a url. this url will be a user domain mask at index 0. after that, i will copy the file from the ram to files. i think this is a brief description how will i do it? Thanks for your time, and waiting to hear more from you.
