To simplify the profiling of your module in Apple Instruments (part of the Xcode bundle), the MeVisLab Project Generator creates a Run in MeVisLab scheme during the Xcode project creation step. If you activate this scheme and click Profile, Xcode will launch the MeVisLab Release version in Apple Instruments and enable you to load and profile your MeVisLab module. The time profile template is activated by default.
