Auv3 UI non-responsive on iOS

Hi, got a strange situation that I wondered if anyone has any thoughts on.

I’ve got an existing project and I’ve just added an iOS exporter for it for AUv3 and standalone.

Fire up the standalone on an iPad and everything works as expected.

But, if I launch the AUv3 with, for example Audiobus, the UI is totally unresponsive - the app is running fine but clicking on anything on the UI has no response.

Anyone come across something similar or have any thoughts? I’ve tried the audioplugindemo and that works fine as expected.

Cheers, Lee

Do you have multiple devices around for testing? It would be interesting to know whether the issue is present on all iOS versions, or just a specific version.

You could also try some other JUCE-based AUv3s to see if they have the same problem (you could start with the demo projects in the JUCE repo), and/or try switching the JUCE version to see if that has any effect.

Hi, yes, have tested on multiple devices as well as in garageband on Mac. Same behaviour. Audio plugin demo works fine so it must be my app, but stumped as to why.

Also, where are AUv3 stored on mac?

They are stored wherever the app is stored that holds it. You can use pluginkit -mv from Terminal to find all appextensions, which includes AUv3.
