Not reflecting latest updated while update pod.

Hi,
When i updated pod in my project from 1.2.0 to 1.2.1 the new update is not reflecting in my project which is for "Fixing block warnings on Xcode 9". Because of this i am still getting warning when i build my application. Can you please help me in this?

Start by reproducing the pod update from version 1.2.0 to 1.2.1 in an Xcode 9 project and check whether the updated code is actually used. Compare the build warnings before and after the update; done means the 1.2.1 pod is integrated and the reported warnings no longer appear.
