I can't reproduce.
By the answers on that link, looks like it can happen if the storyboard gets corrupted somehow, try removing ios folder and running ionic cap add ios again.
Do not remove the Main storyboard, that answer is for iOS 13+ apps that use UIScenes, Capacitor doesn't use UIScenes because they don't work on iOS 11 nor iOS 12 and Capacitor still support them.

Moving to discussions so maybe somebody else can help you.

@jcesarmobile The problem has been fixed!

I tried to remove the 'ios' folder but didn't work for me. What I did is remove @ionic/cli npm package and cocoapods from the macOS. Then I install them again and restart the device. I created a fresh new Ionic app and then build a project to add the iOS platform 'ionic cap add ios', it works!

I have noticed that the iOS project opened in the old Xcode version (11.2.1), and when I build and run it again on the iOS simulator, it crashed. On the other hand, if I opened the latest installed version of Xcode (11.4), and I open the Ionic - ios platform on that version, it works!

It looks like an Ionic/Capacitor needs to be opened directly on the last xCode version installed on the device.

No, Capacitor works on any Xcode 11+ version, I've tested on 11.0 and 11.7 without problems.
Your storyboard probably got corrupted or you had a bad Xcode install.

Thanks for the clarifications! It works well now.
