Answer 1

If you have verified that your Pods have been successfully installed, then the error may be associated with your derived data remaining from before you installed the Pods. You can clear your derived data by going to File -> Workspace Settings... -> Derived Data. Deleting the derived data folder associated with your app and cleaning your build should solve the problem.
