A strange issue with JUCE and XCode

[daniel]

With that limited information one can only guess. It is usually better to start a new thread and add as much information you have of your own problem, instead of assuming you got the same problem.

But I polish my crystal ball and say The error location is in the factory (last lines of the boiler plate), where an instance of your own processor is returned:

// This creates new instances of the plugin..
juce::AudioProcessor* JUCE_CALLTYPE createPluginFilter()
{
    return new YourAudioProcessor();
}

This would fail, if your YourAudioProcessor inherits AudioProcessor (old version) instead of juce::AudioProcessor (new way sinve juce 6).

For more insight see this thread:

JUCE 6: why is a new default plugin project requiring "juce::" in front of everything?

I don’t seem to remember this being the case in JUCE 5… EDIT: OK, I see there is a setting in the Projucer “add using namespace juce to JuceHeader.h” which defaults to DISABLED in a new audio plugin project. Why would you want this to be disabled?

But it could as well be a totally different issue, I am still working on my clairevoyant skills…
