I updated to xCode 7.1 today and tried to build my app but I'm getting this error:
I have already tried going to Build Settings under "Target" and set "Allow Non-modular Includes in Framework Modules" to YES but that didn't solve this issue.
UPDATE: Since this was preventing me from compiling and hindering my progress in terms of development, I recommend you download an older version of xCode from Apple (https://developer.apple.com/downloads/ make sure to login). You can download version 7.0.1 from the link and at least continue development.
This is what I've done and I can continue development.
I know this is not a fix, but its workaround for the people who wish to continue development.
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.
