Does this mean that SwiftKey is now open source, that what they've open-sourced doesn't include the actual prediction engine, or that what they've open-sourced is not the latest version? The GitHub page says they use Presage.

Interesting, since Presage is GPL 2 but this project is Apache licensed. Intel says "Integration with Presage is through the Windows Communication Framework" which I guess is a roundabout way of avoiding the GPL?
The Apache license v2 is GPL-compatible, which was actually one of the major reasons for having a v2.
Apache licensed code can be included in a GPL project, not the other way around. If the project includes any GPL code, the whole thing is GPL.
I think it is better to think of it from the perspective that this code and this project is Apache, but any binaries that result from linking this code to that code are under GPL.
