Install iOS app on simulator

Install App file on Simulator

Apple has introduced an interesting tool with Xcode 6!

simctl

simclt allows you to control the simulators running

run xcrun simctl to get the list of available subcommands. Lots of new options to play around.

Now to do what I wanted. Here is the command to launch simulator

xcrun instruments -w "iPhone 5 (8.0 Simulator)"

-w is to provide device type and to get the list of available devices, just execute this

xcrun instruments -s

After launching the simulator you can control it using simctl

To install you app

xcrun simctl install booted <app path>

To launch the app

xcrun simctl launch booted <app identifier>
