Blocking a website on IOS12

Hi dhiyaafromdallas,

Thanks for using Apple Support Communities. It sounds like you’re trying to block certain websites on your iPhone. I’m happy to provide some steps.

In order to block specific websites, you’ll need to turn on Screen Time and then tap on “Content & Privacy Restrictions.” From there, tap on Content Restrictions > Web Content >”Limit Adult Websites.” Under this section, you’ll see “Never Allow.” Tapping this will allow you to add websites to be restricted.

Take care.
