Apple announced that third-party keyboard support would be a major feature in iOS 8 just two days ago during its WWDC 2014 keynote, and just like that, Fleksy is already showing that it's up and running on Apple's upcoming mobile operating system. The Fleksy keyboard is actually available already on iOS, but only within the Fleksy app itself, as well as in apps that have built-in the Fleksy API. What changes in iOS 8 is that Fleksy (and other keyboards) will be able to take over as the system-wide keyboard for all applications, should a user choose to do that. You can download the Fleksy app now for a preview, and sign up to join the iOS 8 Fleksy beta.
During its WWDC 2014 keynote, Apple announced iOS 8 will support third-party keyboards as part of a new extensions capability. You'll be able to set the new keyboard to be used system-wise, and Apple shows an image of the popular Swype keyboard system as an example. The keyboard will be sandboxed so that they can only access text input, although the user will have the ability to also grant the keyboard network access if there are more features that may require Internet access that someone may want to use.
Third-party keyboards will be available in the App Store when iOS 8 is released.
