Words with apostrophes rarely work

Steps to reproduce

1. Try swiping a word with an apostrophe.

What I expected

For at least the correct word to show up as an option if it doesn’t appear as the word that actually appears.

What happened instead

More often than not the correct word doesn’t show up anywhere. Other times, a form of the word that isn’t a real word appears instead of the correct version (Im instead of I’m).
