The project builds and runs successfully according to Xcode, however, the .VST3 and .component files are not created and are highlighted in red under Products in the Xcode browser. The .app file is created in the specified location and runs as expected displaying the GUI with a functioning slider.
I’m running Projucer with JUCE version 6.0.7. According to the tutorial:
“All of the files that you need to create VST3 and AU (MacOS only) plug-ins are packaged with JUCE (as long as you are using a recent version of JUCE).”
What’s showing in the scheme dropdown next to the Play/Run button in Xcode’s top bar? To build the AU/VST3 components, you’ll need to select the relevant item from that dropdown before building - or select the “All” scheme.
Next to the start/stop buttons. That’s the target that will be built. So you need to select All there if you want to build everything.
Or create a script that builds everything, package, notarize…
Usually I just build the standalone plugin in debug with Xcode, the rest is command line to automate the process.
