Select your pod from the left project navigator. > Select Target. > Select "Build Settings". > Build Active Architecture Only to No

In my case

pod deintegrate
pod clean
pod install

I turned it off (tried to fix another problem) and spent quite some time trying to fix the build.

I had the same problem with Xcode 10 and newly added pods.

I've noticed new pod was not added to Target -> Build Phases -> Link Binary With Libraries. When I added new pod-framework manually, archiving worked ok.
