Hello!

This it more related to Xcode, rather than IPlug, so I might be posting on the wrong forum. But maybe people here have experienced a similar problem. Basically, everytime I build my project for AUv2, my DAW (Logic Pro X) rescans all of my other AudioUnits. This is very unefficient since I have close to 400 AUs and cant use my computer while it scans.

I also dont use Logic for debugging AUs (it’s not associated with Xcode at all), so it seems rather unnecessary. I’m guessing it has something to do with the auvaltool…
