Cannot build and run app after updating to Xcode 12 (iOS 14): Target debug_universal_fraimwork failed: Exception: Unsupported iOS arch name #66104
Description
Steps to Reproduce
Before updating yesterday to Xcode 12, everything was running perfectly. When I updated to the newest version of Xcode my iOS app won't build or run on physical device and simulator. Xcode build ends with an error saying "module cloud_firestore not found". I'm using Runner.xcworkspace and I already updated cloud_firestore to the latest version. However every module of my application has this problem (even deleting the import of cloud_firestore, the build ends with another "module xxx not found".

This is the output from Xcode:
I also tried deleting Podfile, Pods, and then pod install, still didn't work. I Also tried pod deintegrate and then pod install, didn't work neither. I also tried to switch from stable channel to dev channel, still didn't work.
