Better iOS 10 Keyboard
Apple delivers a massive iOS 10 keyboard upgrade to users. There was no mention of better support for third-party keyboards, but the new stock iOS 10 keyboard is very handy.
Siri's artificial intelligence is part of the keyboard. This means that when you type something with a lot of mistakes, there is a better chance that auto-correct will get you to the right thing.
Other cool Siri-like features bring intelligent sharing right to the keyboard's predictive text. If someone asks where you are, you can tap to share your location. When someone asks for a contact's phone number you can tap to share it.
Locally Siri knows what you've been doing when you are using iOS 10, allowing the keyboard to know that you want to make a calendar appointment for brunch at a specific location and time.
You'll also see calendar information in the predictive area of the keyboard and much more.
