Ionic app crashes in iOS, fine on Android

My app crashes every time I attempt to test it on iOS - both in XCode and via the CLI. It works flawlessly on Android. Via the CLI I am not getting any error messages, but it still shuts down immediately in the emulator and on a device. When I build through XCode I get an error message, but I can’t for the life of me figure it out. I’ve included a screenshot of the error here.
Please help if you can!

Check the plugins you are using. Plugins have different code on ios and android so the ios version might have a problem. Remove all plugins and add one by one to isolate the problem.
