Failed to run a react-native app in iOS 11 - 13.2.2

[theo82]

So I have been running my app on an Android device and works fine as shown below.

However, I can't test it on an iOS emulator. I load the emulator by typing

open -a simulator
It opens up. Then I type npm run ios and get this back.

`error Failed to build iOS project. We ran "xcodebuild" command but it exited with error code 65. To debug build logs further, consider building your app with Xcode.app, by opening confusion.xcodeproj

** BUILD FAILED **


The following build commands failed:

My package.json file is this

Is there any way to fix this? Thanks.
