E aqui fica um artigo. Esta solução do clique com os dois dedos parece-me melhor do que a existente em SO's anteriores (ainda estou no iOS 10).
Quickly Open Link In A New Tab With A Simple iOS 11 Safari ShortcutWhen you are browsing the web on iOS 11 powered iPhone or iPad in Safari, you can simply tap on a link with two fingers. Once you do it will automatically open in a separate tab without interfering with the current webpage that you are viewing. When tapping with two fingers make sure you hit the link with both fingers at the same time for this shortcut to work.
This feature is more useful on devices that are not iPads and don’t have 3D Touch functionality. This simple Safari shortcut makes web browsing experience much better and saves user a lot of time.
