There will be times where you want to do these on the command line.

List the available SDKs

xcodebuild -showsdks

For example, I have iphonesimulator8.2 in my list of SDKs. This will be used in the next step.

Xcode Build

Build the project:

xcodebuild -project '/path/to/Awesome.xcproj' -arch i386  -sdk iphonesimulator8.2

If you are using workspace, then you need to provide the scheme too:

xcodebuild -workspace '/path/to/Awesome.xcworkspace' -scheme 'Awesome-Production' -arch i386  -sdk iphonesimulator8.2

Or, more likely, you are using Xcode app (not commandline), then just build the app as per normal.

The build will be created at ~/Library/Developer/Xcode/DerivedData.

So, if the build is successful, the app will be at ~/Library/Developer/Xcode/DerivedData/Awesome-dvxamtpiqakwogarovbwiagepzxj/Build/Products/Release-iphonesimulator/Awesome.app. This path is needed in the next step.

Run on Simulator

Use ios-sim to help run on simulator.

Install it with brew install ios-sim.

Then run:

# First, find the device type
ios-sim showdevicetypes
# Example using iPhone 6 Plus
ios-sim launch --devicetypeid "iPhone-6-Plus, 9.2" /path/to/awesome.app

That’s it!
