This came from an answer already posted, but there was a part missing in the GitHub issue I didn’t get at first.

To fix this you need to Open Xcode and set Allow non-modular Includes In Framework Modules to Yes.

Xcode setting to change

You can do this by:
- Opening up the ios folder of your app in Xcode
- Click on Runner > Then click on Build Settings
- Make sure All is selected in the filter bar
- Search for Allow to find the setting to toggle to Yes
This cleared up the issue and my app was able to be built and launch on the simulator.
