Use XCode’s ready-made Cocoa user interface building blocks and connect them with your Cinder + OpenGL sketches’ magic.
Have several Cinder sketches within the same app, be it in the same window on the Mac or in tab views on iPhone & iPad.
Use Cocoa Touch image picking from the album or from the camera, have popover views with custom appearances...
Both iOS & Mac wrappers are built to work with the latest official release: as of right now (August 2015), that's version 0.8.6. The examples and the XCode templates provided on this website and on the repositories are ready to use with that official release of Cinder.
If you feel more adventurous and want to compile the latest Cinder, go right ahead, the community is so awesome people will help you through the process. Though be aware that you might have to modify the wrappers at some point if core changes are made in Cinder's github version.
