How can a developer configure remote iOS simulator launching via terminal and automate building?

To automate the development and testing of mobile applications, developers often need to manage iOS simulators directly from the command line without launching the heavyweight Xcode interface. This allows building and testing processes to be integrated into continuous integration systems.

The primary tool for working with simulators from the terminal is the `xcrun simctl` utility. With it, you can list available devices, launch them, install apps, and simulate various system events, such as changing geolocation or receiving push notifications.

To view a list of all available simulators and their udid identifiers, run the command `xcrun simctl list devices` in the terminal. Find the required device and copy its unique identifier for further work with automation scripts.

To launch a specific simulator, use the `xcrun simctl boot` command specifying the device's udid. After that, you can open the Simulator GUI application using the command `open -a Simulator` to visually observe the testing process of your software.

Building the application for the simulator from the terminal is performed via the `xcodebuild` utility. Specify the path to your project, the build scheme, and the target platform, after which the compiled file can be installed onto the running simulator using a single installation command via `simctl`.
