iOS building for iOS Simulator, but linking in object file built for iOS XCode12

The error log is as follows

building for iOS Simulator, but linking in object file built for iOS

Today I upgraded XCode12 and found an error in emulator compilation:

The linker link reported an error: building for iOS Simulator-arm64 but attempting to link with file built for iOS Simulator-x86_64 Xcode12 emulator already builds projects using ARM architecture, while link links to x86 architecture

Temporary fix: Target — Build Settings have the VALID_ARCHS at the bottom. These VALID_ARCHS have been deprecated in XCode12, but some of cocoapod’s integrated tripartite libraries still have this key, such as this Aurora authentication:

Find it in the project Target — Build Settings

Add a x86_64

The app file will not have access to the VALID_ARCHS file if the VALID_ARCHS value is deleted

I’ll be able to run properly after adding the X86_64 to the VALID_ARCHS
