No luck for me either. It seems I can only create a parameter tree in the initializer: (instancetype)initWithComponentDescription:(AudioComponentDescription)componentDescription options:(AudioComponentInstantiationOptions)options error:(NSError **)outError I find it incredible this problem still exists, I reported it in 2018. They got back to me in 2020, and I didn't have time to revisit the issue until now. Here's my report in the feedback assistant: not sure you all will be able to see it: https://feedbackassistant.apple.com/feedback/5416436

I have this problem with JUCE 7 when building the Projucer - is there an official explanation dear Apple?

Xcode 13.4 13F17a does not a a problem with the project To test it out, please do the following: git clone https://github.com/juce-framework/JUCE.git cd JUCE/extras/Projucer/Builds/MacOSX open Projucer.xcodeproj Then make an archive

Thanks saxmanbob. Seem my additional comment below.

For our particular problem we filled a Feedback Assistant ticket on June 12 (FB13878109) Aside from a single response on July 2 requesting additional information, we have not received any further communication from Apple. You can see our developer forum thread here: linkText
