iOS Emulator WSOD

For some reason, my app is working fine with ionic serve and on an Android device, but it is not working on an iOS simulator. It gives me a WSOD.

I checked the console for it (using Safari inspector) and all it tells me is that it cannot find index.js.map.

I originally had the phonegap-plugin-push plugin installed which gave me a lot of warnings when I would build the app for iOS, so I removed it but it didn’t fix the issue.
I tried reinstalling the google maps plugin, but that didn’t help.
I went through this: https://github.com/driftyco/cordova-plugin-wkwebview-engine#installation-instructions, but that didn’t help either.

Any other ideas?

Update: I tested it on an iOS device using the ionic view app and it gave the same WSOD.

In one of my providers I forgot to reference Storage. It did not completely fix the issue, but it may have had something to do with it.
Now it runs with the command ionic run ios -l -c, but it doesn’t run without those tags.
