Target 'AAA-Pods' for project 'Pods' was rejected as an implicit dependency for 'Pods_AAA.framework' because its architectures 'x86_64' didn't contain all required architectures 'i386 x86_64'.
This appears as warning, then linker error appears.

On a very new project on Xcode 9.4.1, the issue was that my Podfile's deployment target was set to platform :ios, '11.0' while my project's iOS deployment target was set to 10.3.
This caused the generated Pods project to target iOS 11.0 (supported by only 64-bit devices on arm64 architecture), but since my main project targets 10.3 and includes armv7 devices, this doesn't work when archiving a Release build since a Release build also builds nonactive architectures by nature (unless you only support iOS 11 devices).
The fix then is to simply change the Podfile's deployment target to match your main project's, in my case it's platform :ios, '10.3'. Afterwards, run pod update and the Pods project should be regenerated. Launch Xcode, perform a clean and you should be able to run the archive process.
I had the same issue recently after migrating to Xcode 10.1.
Building with Debug config was working just fine, however archiving with Release config was generating this warning. And then archiving would fail, because in the main project all the module imports referring to Pods were failing.
Checking the Build Settings for the Project I realised that iOS Deployment Target was showing a different value for my Release config.
iOS 10.0, while my Podfile was set to platform :ios, '11.0'.
