I am making an app which will support the "Add to Homescreen" features in Android Chrome and iOS Safari. Since I would like universal offline support for both of these features, but I only want to use the manifest file where I have to, in order increase my control. However, iOS Safari does not support service workers, so my question is how can I only instantiate a cache manifest file if support for Service Workers is not present, more specifically; I know I could add manifest='whatever.appcache' to the <html> tag with JavaScript, but will browsers, specifically iOS Safari, use that cache?

this is an excellent design! (Service Worker with fallback to AppCache) – code_monk Dec 04 '16 at 04:17

According to an answer by @Daniel Herr:
You could choose to use Service Workers and AppCache on the same web app. What happens in such a case is that browsers that don’t support Service Workers will use AppCache, and those that do will ignore the AppCache and let the Service Worker take over.
