-fobjc-weak is not supported on the current deployment target

Asked 6/2, 2018 at 12:45 Answered 6/2, 2018 at 16:3

I just updated my Pods and one of them BoringSSL is now eroring my build with following error:

Apple LLVM 9.0 Error
-fobjc-weak is not supported on the current deployment target

Not sure about what I need to do here? Is this an issue with BoringSSL package or my project?

EDIT I believe this is used by grpc ?

This is CocoaPods/Xcodeproj#544 for which a fix was released recently.

Update the Xcodeproj gem from 1.5.5 to 1.5.6.

I see, since I am a new user to cocoapods would you mind giving a detailed guide on updating Xcodeproj gem? – Illfounded 6/2, 2018 at 17:27

gem update xcodeproj may work, but it depends upon how ruby and CocoaPods are installed. – Lilias 6/2, 2018 at 20:12
