Learn what it took for our team to replicate the visuals and interactions of the system keyboard so we could provide users with a smooth transition to our keyboard powered by Grammarly functionality. You will be surprised that it requires a bit more than creating 30 UIButtons. We will discuss different animations and interactions that we had to implement. We’ll also describe how we attained feature parity with the system keyboard regarding emoji, which some other third-party keyboards don’t offer. Finally, we’ll explain why original architecture decisions may not always be bulletproof, even for such a simple thing as a keyboard.
