why does swiftkey keep stopping

[AC Question]

each time I go to type a text message I get the following: Swiftkey has stopped working. By repressing the space to type a message swiftkey comes back, but it is very annoying !!

Welcome to Android Central! Which phone? Go to Settings>Apps​, select Swiftkey, and Clear Cache. Does it still happen after that?
