Xcode compile failed to the JUCE Demo plugin

Also mind this thread:

VST SDK v3.6.7 and compiler error when building JUCE plugin

Thank you for reporting. The new VST3 SDK is almost completely different, and supporting it in JUCE (and getting it properly tested) is too big a job to do before the release of JUCE 5. One highlight of the new release: “this maintenance release is mainly a preview version for Linux support” but I’ve not found any more information about what “preview” means in this context…

So check also the version of your VST-SDK to match the version of JUCE

Good luck
