iPhone Simulator
The iPhone Simulator is part of Xcode. Rather than trying to create a project in Xcode to start the simulator, use this command in a Terminal window:
open /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/Applications/iPhone\ Simulator.app
Alternatively, create a quick shell script:
#! /bin/sh
open /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/Applications/iPhone\ Simulator.app
Save the script into a directory on your $PATH with a meaningful name, like iphonesim. Then you can just run:
iphonesim
to start the simulator
