Xcode 12, building for iOS Simulator, but linking in object file built for iOS,

解决方法：

Bulid Settings->Architectures->Excluded Architectures->Debug->Any iOS Simultator SDK arm64

如果项目还引入了cocospod。还需要配置

s.pod_target_xcconfig = { 'EXCLUDED_ARCHS[sdk=iphonesimulator*]' => 'arm64' }
s.user_target_xcconfig = { 'EXCLUDED_ARCHS[sdk=iphonesimulator*]' => 'arm64' }
