Can't find AudioProcessorValueTreeState?

Very odd. I just created a brand new plugin project with Projucer 4.2.4 and opened it in Xcode 8. When I added the following line in my processor .h file, it complains::

ScopedPointer<AudioProcessorValueTreeState> vt;

Use of undeclared identifier 'AudioProcessorValueTreeState'

If I remove that line, it compiles just fine. What’s going on? I just recently updated to 4.2.4, but everything else is compiling fine.


I changed the OS X Deployment target to 10.9 and everything is now fine.

I guess that means ValueTrees require 10.9 minimum. ?

I believe it needs c++11 support
