Undefined symbols for architecture arm64

Question

I'm using a framework which someone else has written and I've included it in my project.

I run my application with xcode 6.1, i'm getting O-linker error 'Undefined symbols for architecture arm64'

Can anyone help me to resolve this issue?

Answer 1

There is no equivalent to thunking between 64 to 32 bit code: too much has changed (see: 64-Bit Transition Guide for Cocoa Touch).

The only solution is get the framework author to rebuild the framework with 64 bit support. If that is not possible, then you need to replace the framework with a different framework which does support 64 bit.
