The (unjailbroken) iPhone's Safari cannot access the local file system, so it's impossible to download anything.

(The iPad, OTOH, may support it.)

use the download attribute in slide your a tag

<a href="content/file.pdf" download > pdf link </a>
<a href="content/file.doc" download > doc link </a>
