Thanks to all of you. By browsing this thread I found a simple solution. Rather than doing a factory reset or ignoring the error, I decided to try uninstalling and reinstalling SwiftKey. It worked. It took about 3 minutes...much shorter than a reset, and a lot less hassle. So my recommendation is to uninstall SwiftKey, restart your phone (may not be necessary, but I did it for good measure), and re-install SwiftKey. Once I did that, I had no problems whatsoever. So before you do the reset, try uninstalling and reinstalling SwiftKey first and see if that fixes the issue.
