I add arm64 to my app:

Architecture
Valid Architecture

And when i build the application i get this error log:

Undefined symbols for architecture arm64:

      objc-class-ref in DEFacebookComposeViewController.o

Any idea what can be the problem?

I update the googleadmob lib and facebookSdk but the other Framework already support the 64bit and i get this error msg:

Answer 1

The error messages are pretty clear. Those symbols are not defined for that architecture. You'll need a new build of every one of those libraries - a build that has a 64bit slice.
