JournalingSuggestions crashes on iPad and won't build on Simulator even if the library is marked as optional

This is a major issue. My iPad app is crashing in the App Store. In order to fix it, I found a post that recommended making the framework optional. I did so. Now I can't compile on simulator and besides, it did not fix the iPad App Store crash.

ld: framework 'JournalingSuggestions' not found
