Apple's Craig Federighi showed off new intelligent typing features in iOS 8 at the WWDC keynote today. Dubbed QuickType, the new iOS 8 keyboard is context-sensitive and introduces predictive word suggestions.
A new row added to the top of the keyboard allows you to pick from predictions for your next word, and this is sensitive to the context of the message and the person you're talking to, with communication styles adjusted accordingly.
For instance, today's demo showed off messages about going for dinner or a movie, and showed that word predictions changed to show "dinner" and "movie" for new messages in the thread.
The new keyboard features in QuickType will support fourteen regions — U.S., U.K., Canadian and Australian English, Brazilian Portuguese, Chinese (including Hong Kong and Taiwan), French, German, Italian, Japanese, Spanish and Thai.
