cool. I was just shopping for a new growing text view since HPGrowingTextView seemed like it was not maintained and buggy on IOS 8.

I settled on https://github.com/oseparovic/MessageComposerView.

It's nice, simple, and does the trick. However, I will definitely checkout SlackTExtViewController.

For people not in IOS development: yes this is crazy that it is not built in. But our tool chain is better :)
