Need help with CorePlot implementation for iOS 11 app

[Ryan C]

I am trying to update an old 32-bit app to 64-bit so that it can run on iOS 11. I'm using Xcode 8.0 and am building with standard architecture arm64 and armv7. When I try to build the project, this error comes up:

Undefined symbols for architecture x86_64:

  "_OBJC_CLASS_$_CPTColor", referenced from:

      objc-class-ref in PenetrationPlotViewController.o

  "_OBJC_CLASS_$_CPTPlotSymbol", referenced from:

ld: symbol(s) not found for architecture x86_64

clang: error: linker command failed with exit code 1 (use -v to see invocation)

I have the latest version of core plot downloaded from GitHub from this site: https://github.com/core-plot/core-plot

and I tried the iOS application method on https://github.com/core-plot/core-plot/wiki/Using-Core-Plot-in-an-Application.

Does anyone know a fix to this or if I'm missing something?

Thank you!

Sorry for the late reply. Were you able to resolve this problem or do you still need help?
