ofxICalendar compile error - invalid deployment target for -stdlib=libc++

Trying to compile the example using latest Ofx 0.9 targeting the latest OSX SDK 10.11 and get the following error

invalid deployment target for -stdlib=libc++ (requires OS X 10.7 or later)

Anyone have an idea how I might resolve?

Have different compile errors now but the issue was straightforward

In Build Settings > Deployment I was targeting 10.6
