Question

I want to launch iPhone simulator from command line.

until now I have been using the below command

/Applications/Xcode.app/Contents/Developer

Answer 1

Run this command. The app will be restarted followed by changes. No need to rebuild it again.

ios-sim "launch" "/Library/WebServer/Documents/testapp/build/iphone/build/Debug-iphonesimulator/test.app" "--devicetypeid" "iPad-2" "--exit";

For devicetypeid list:

ios-sim showdevicetypes
