Unable to compile AU for Mac or AUv3 for iOS after enabling AUv3 option for plugin type. It does not work after disabling the plugin type, renabling on one from AU or AUv3, clearing build folder, clearing Xcode derived data, all.
There might be an issue in the expansion of that JUCE_AU_ENTRY_POINT_NAME macro.
What’s the exact name that you have given to your plug-in? Does it contain any “fancy” character?
