Our app uses CoreNFC to scan NFC tags or you can use QR if NFC is not supported. This worked pretty well and we were able to run the app in the simulator for (ui) testing purposes.
Until Xcode12 / iOS14 GM builds. In iOS13 (or lower) we wouldn't have any issues running it on a simulator.
But in Xcode12 running it on a iOS14 simulator iPhone11 we would get the following:
That the simulator crashes makes sense to me, since the simulator can't scan NFC tags, but this is what I've done:
Running it from Xcode12 on an iOS13 simulator 'device' works perfectly. So I can't seem to figure out what is causing this behavior

That the simulator crashes makes sense to me, since the simulator can't scan NFC tags, but this is what I've done:
I already linked to the CoreNFC framework and made it optional.
Put #if canImport(CoreNFC) around import CoreNFC and it's underlying NFC code.
Cleaning the build folder and deleting derived data.
Created an empty Xcode12 project: https://github.com/basvankuijck/CoreNFCCrashProject, same result.
Removed all the listed simulators and re-added one
Added -weak_framework "CoreNFC" to the Other Linker Flags build setting
