Any news? I have the same problem here... MacBook Pro 16 Late 2019 macOS Catalina 10.15.6 Xcode 12.0.1 When I launch simulator from Xcode the Spotlight process crashes and then the Report Crash process starts to consume a high amount of CPU making all other apps slow...

Same issue here with MacBook Pro 16" 2019, macOS 10.15.6 and Xcode 12.0.1. Spotlight keeps crashing and causing terrible performance.
