xCode 7 error: include of non-modular header inside framework module with Google Maps
Google has updated its SDK to 1.10.5, Just Reinstall Pod and it should work fine. I was facing same issue and now all issues are fixed after pod reinstallation.
I ended up having to create an Objective-C bridging header file and adding #import <GoogleMaps/GoogleMaps.h> whereas I hadn't needed one previously since I was using Cocoapods in a Swift project and the use_frameworks! setting had previously taken care of this.
Here's instructions for how to create the Objective-C bridging header file: (https://developer.apple.com/library/ios/documentation/Swift/Conceptual/BuildingCocoaApps/MixandMatch.html)

Just remove the header search paths in build settings. In new Xcode versions (after 7.0 I guess) you need to look for the headers by linking frameworks and not by linking header files directly.
