Xcode – Project build succeeds but lots of errors appears when previewing

My project builds fine, but when i build as previewing it shows lots of errors. Have already restarted my Mac and used pod install and pod update, but it still persists.

The screenshot that shows an error in the code isthe only error that refers to some code, the other "red" errors don’t refer to any fisic code

Edit: FAIL DIAGNOSIS:

Build target FirebaseCoreDiagnostics:
warning: The iOS Simulator deployment target ‘IPHONEOS_DEPLOYMENT_TARGET’ is set to 8.0, but the range of supported deployment target versions is 9.0 to 14.1.99. (in target ‘FirebaseCoreDiagnostics’ from project ‘Pods’)

    I think the correct pod is pod ‘FirebaseCore’, not pod ‘Firebase/Core’. Try changing that pod and see if it works. Some of the "yellow" errors will remain, but the app should still build.

    Your problem is here as written :
    The iOS Simulator deployment target ‘IPHONEOS_DEPLOYMENT_TARGET’ is set to 8.0, but the range of supported deployment target versions is 9.0

    Copy and paste this code to your podfile. After go to terminal and make pod update

    post_install do |pi|
    pi.pods_project.targets.each do |t|
      t.build_configurations.each do |config|
        config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = '9.0'
      end
    end
end
