Markup feature in images in swift

I've created a chat app, where user can chat and share images. Now I need to add feature where user can edit and perform some annotation on images. I've heard from iOS 9 there's a new feature called markup to perform editting on images. I've checked UIActivityViewController and couldn't find in it. Is this feature available and can it fit to my requirement? If not, is there any other alternatives that I can approach?
