Allow user to download file from website ios swift

Note that you can have multiple web servers running in the same app as long as they listen on different ports.

Then you add one or more "handlers" to the server: each handler gets a chance to handle an incoming web request and provide a response. Handlers are called in a LIFO queue, so the latest added handler overrides any previously added ones. GCDWebServer relies on "handlers" to process incoming web requests and generating responses. Handlers are implemented with GCD blocks which makes it very easy to provide your own.

However, they are executed on arbitrary threads within GCD so special attention must be paid to thread-safety and re-entrancy.

Here's an example:. Advanced asynchronous version The handler returns immediately a streamed HTTP response which itself generates its contents asynchronously:. Note that you can even combine both the asynchronous and advanced asynchronous versions to return asynchronously an asynchronous HTTP response! When doing networking operations in iOS apps, you must handle carefully what happens when iOS puts the app in the background.

Typically you must stop any network servers while the app is in the background and restart them when the app comes back to the foreground. This can become quite complex considering servers might have ongoing connections when they need to be stopped. HTTP connections are often initiated in batches or bursts , for instance when loading a web page with multiple resources. This makes it difficult to accurately detect when the very last HTTP connection has been closed: it's possible 2 consecutive HTTP connections part of the same batch would be separated by a small delay instead of overlapping.

Both for debugging and informational purpose, GCDWebServer logs messages extensively whenever something happens. Amul Amul 1, 12 12 silver badges 27 27 bronze badges.

But at the time of writing this June, , documentation is still quite limited: WKDownloadDelegate 1. WKNavigationDelegate 1. WKDownloadDelegate 2. You need to assign a delegate to each download, but it can be the same delegate for all of them. Final notes Remember both delegates are not retained by the WKWebView, so you need to retain them yourself.

There are a few more methods on WKDownloadDelegate useful for dealing with errors, check the documentation for more details link provided above. Important to remember this is only supported on macOS As mentioned before, documentation is still scarce, I just finded how to make this work by trial an error, any feedback appreciated.
