1. In the Mac terminal, using Brew to install OPENCV3, my OpenCV is installed in/usr/local/cellar/opencv3/3.2.0.

2. Create a new Xcode project, select command Line tool, create a new group within the project directory, and add the dylib containing LIBOPENCV within the/usr/local/cellar/opencv3/3.2.0/lib.

3. Change header search Paths to/usr/local/cellar/opencv3/3.2.0/include in build settings, Library search Paths more/usr/local/ Cellar/opencv3/3.2.0/lib. Note that this cannot be copied online only/usr/local/include or/usr/local/lib, depending on your OPENCV installation address
