error messages:

Implicit declaration of function 'CPTQuickLookImage' is invalid in C99

Please explain about the CPTQuickLookImage class not available in side the framework/source/ path

The CPTQuickLookImage() function is defined in the platform-specific functions file. The compiler can't find the right header file.

What version of Core Plot are you using? How is it imported in your project (dependent build, dependency manager, Swift PM, etc.)?

[arunmahask]

i am using core plot version 2.3.

i have imported by using pod. i am using this version for objective C project, not swift project.

now the project run successfully, but i am having issue, i.e "ld: framework not found CorePlot
clang: error: linker command failed with exit code 1 (use -v to see invocation)"

When i am trying to archive the project to upload in testflight.

This should be fixed on the release-2.4 branch. Let me know if anyone is still seeing this issue with the latest code.
