Run iPhone/iPad Simulator for Continuous Integration

To launch a specific device you can do:

/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/Applications/iPhone\ Simulator.app/Contents/MacOS/iPhone\ Simulator -SimulateDevice "iPhone Retina (3.5-inch)"

Try this in your shell for Xcode 6

osascript -e 'activate application "iOS Simulator"'

For Xcode 7

osascript -e 'activate application "Simulator"'

If you want to open Simulator with specific app installed then you can use some of the ready utility to launch simulator. This way it is easy to install the app and run on the simulator. This are the command line utilities that can be run from Terminal Window.

1. iPhoneSim
2. ios-sim
3. Other are same as above two.

And main thing is all uses same approach to open simulator. (see the project for more details)

Other way (not recommended by me) use script file to run from command.

Use the -SimulateApplication argument to run your executable in the simulator (executable inside the .app bundle)

(you could also compile the project from the command-line like this:) xcodebuild -project Test.xcodeproj -arch i386 -sdk iphonesimulator

Then for example:

/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/Applications/iPhone\ Simulator.app/Contents/MacOS/iPhone\ Simulator -SimulateApplication Test.app/Test

or

./Developer/Platforms/iPhoneSimulator.platform/Developer/Applications/iPhone Simulator.app/Contents/MacOS/iPhone\ Simulator -SimulateApplication Test.app/Test
