Xcode 12 - No architectures to compile for (ONLY_ACTIVE_ARCH=YES, active arch=x86_64, VALID_ARCHS=arm64e armv7s arm64 arm7)

Since I update Xcode to Xcode 12, I've got this error when I build :

Check dependenciesNo architectures to compile for (ONLY_ACTIVE_ARCH=YES, active arch=x86_64, VALID_ARCHS=arm64e armv7s arm64 arm7)

I try a lot of things :

• Uninstall/reinstall Pods via pod install
• Build Active Architecture Only to No or to Yes for Debug and Release
• Same thing for Pods project

Don't know what to do. This error come when I want to launch on iOS 14, but in iOS 13.7 this work perfectly without change.
