I am trying to solve a problem that led me to this help page here where if you are having issues with an iOS device simulator, the recommended solution is to
If your problem is on iOS, try: 1. Close all simulators/device builds 2. Stop the package manager running in terminal (or better yet, just restart terminal) 3. Open the ios folder in your app root in finder 4. Go into the build folder (note: you won鈥檛 see this build folder in atom, so just right click ios and click open in finder) 5. Delete everything inside of the build folder (just move to trash and keep trash around in case you鈥檙e worried) 6. Run react-native run-ios to rebuild the whole thing
However it seems like react-native run-ios does not rebuild the whole thing, as after deleting everything in that folder I am running into these:

I'm getting the same issue. After react-native link realm I get the error below.

Reverting to version 2.0.13 fixes the issue.
Reverting solved that error, however after running react-native link realm, I ran into this
