Answer 1

As an interim solution you can remove armv7s from the Architectures in the Xcode project. Change "$(ARCHS_STANDARD_32_BIT)" to "armv7". When the libraries are updated change back to re-add armv7s support.

Answer 2

Facebook sdk isn't compiled for armv7s, but you can compile yourself

Look at Liam nichols answer here

https://developers.facebook.com/bugs/107674376052717/

Download a copy of the source code from the git hub page (facebook git hub) Open up the xcode project and in the build settings change the architecture to armv7, armv7s Close the project Navigate to /scripts and in terminal run ./build_all.sh When it finish compiling, you can find the framework in builds/FacebookSDK.framework
