here is the project.
as I wrote, I took the one by dave96. It worked.
I changed some UI stuff, place etc. it worked.
I opened the .jucer file with introjucer in order to change the project from Applications to Audio Plugin, save & open with Xcode.
And here is the error.
I rechecked, libs are correctly linked no?
