Pinned Contacts
Now there’s a new, easy way to pin your favorite conversations and contacts on the Messages app.
Pinning your contacts is as easy as you would expect from Apple. All you need to do is select the conversation you want to pin, swipe it all the way to the right. You should see a yellow pin next to your contact.
Every time you go into the Messages app you’ll first see the picture of your pinned contacts at the top, followed by every other conversation.
