SwiftKey, Swype and Fleksy have already started to work
Since Apple made the announcement that it is going to allow the third party keyboards for the iOS 8, everyone has been thinking whether this would mean if the better known Android keyboards make the leap or not. To keep it short, we would likely say the answer to this confusion is yes. Because according to SwiftKey, their heavily customizable software is already being ported to the iOS. And we don’t just have one player in this; according to Engadget, Swype is overly excited and it just can’t wait to be one of the supporters of Apple’s platform.
Then we also have Flesky, which is also equally excited at the idea of serving Apple’s cause but it might just have landed a bit too far and is already taking sign-ups for a beta program and is sure that it is going to be "one of the first" with a solution.
The odds of having a Google keyboard on your iPhones are currently not running that high but we still need to receive more information to be sure of anything. But we are surely expecting some smashing input methods when the iOS 8 comes to us this fall.
