In a family there probably are a bunch of people who are friends with more than one family member. Or in a company there may be lots of people that many employees are in regular contact with. So how do you solve that in iOS? As far as I know, there's no easy way copy contacts between iPads and iPhones in iOS.
Apples free Shortcuts app is my solution. I have built a very simple shortcut that lets you pick any number of contacts and share them any way you like, for instance by email, messages, Airdrop or Slack. So uncomplicated, but fast and time saving. Download the shortcut below when you have installed Shortcuts.
