Tested without any plugins or changes.

Steps to reproduce:

This was fixed here #1242
I have replaced the contents of the CAPPluginCall.swift file with this pull request, which you sent and the error still occurs.
Have you done a product -> clean build folder before running? Xcode 10 doesn’t rebuild cocoa pods projects
Yes, I done it. Please test on XCode 10.2 beta 3
Sorry, you are right, this is a different issue
This crash is only happening when I deploy to a device with iOS 12.2. For an older phone or iOS 12.1 or lower, it won't crash. I'm getting this error below.

Message from debugger: Terminated due to signal 9
Capacitor 1.0.0-beta.17
I have the same problem with vanillaJS and vueJS, so it's not connected with react-native.
Crash on 12.2-12.3, all works fine on 12.1 and lower.

Capacitor 1.0.0-beta.19
I can confirm this issue has been resolved with capacitor 1.0.0-beta.19.
make sure you have "@capacitor/ios": "^1.0.0-beta.19" in your package.json, not just the CLI 1.0.0-beta.19.
Then do npx cap update ios, npx cap open ios and finally Product -> Clean Build Folder on Xcode, as Xcode 10 doesn't rebuild the changes in CocoaPods libraries and the clean makes it build on next run.
