Apple Mach-O linker errors While Archiving My project

Question

I am trying to archive my First iOS Project and I get the following errors. It seems like there is something bugged with the Facebook SDK and Google Plus SDK which i have used for Authentication. I have come across similar questions on stackoverflow but none's solutions helped me. Any help would be appreciated. Thanks in advance.

Answer 1

The framework you are using is not arm64 ready, ie not for 64bit devices, you can either check if an updated framework is available, or exclude arm64 that from your build

Set the architecture in build settings to Standard architectures(armv7,armv7s)
