Xcode Profile vs Analyze
•Run will build and run the target on the selected device or simulator.
•Test will build your target and run its unit tests (YourTargetNameTests.m)
•Profile will build and run your target on the selected device or simulator with an Instruments tool of your choosing (Leaks, Allocations, etc.)
•Analyze will build your target using the static analyzer and let you know of certain types of bugs in your code.
