Sender Synth example can't build - symbol(s) not found for architecture arm64

问题

I have follow the Sender synth example, with XCode 10.1, Audiokit 4.5.5. But when I try to build it (part Audiobus and Integration), it fails with this error:

   Undefined symbols for architecture arm64:
  "_OBJC_CLASS_$_ABPort", referenced from:
      objc-class-ref in Audiobus.o
  "_OBJC_CLASS_$_ABAudiobusController", referenced from:
      objc-class-ref in Audiobus.o
  "_OBJC_CLASS_$_ABAudioSenderPort", referenced from:
      objc-class-ref in Audiobus.o
  "_OBJC_CLASS_$_ABAudioFilterPort", referenced from:

ld: symbol(s) not found for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

I tried to build with my iphone SE connected via usb and with Audiobus app installed on it. I tried also targeting simulator, but same error occurs with x86_64 rather than arm64. I searched and try many things but did not find any solution. I read many times the tutorial but I don't see anything I forgot. What is missing. Could someone help me please?

回答1:

These are symbols from the AudioBus SDK; you need to link with the SDK and using your API key to resolve these errors.

回答2:

If you have this issue, try adding "$(inherited)" to your targets build settings under "other linker flags".
